We’re endlessly fascinated by the breakfast, lunch, and dinner choices of celebrities. Welcome to My Morning Routine , where we talk with musicians, actors, politicians, and athletes about how the foods they start and end their day with—and everything in between.

At 29 years old, Alex Honnold is one of the most famous and accomplished rock climbers in the world. He often free solos (climbing alone and without ropes) and is best known for a seemingly effortless approach to scaling the biggest, most dangerous peaks in record time. When he's not climbing, Honnold lives out of a van and does sustainable energy work through his charity, the Honnold Foundation . We were curious: What foods fuel a man who scrambles up Yosemite's Half Dome in under an hour and a half? We spoke with Honnold over the phone; read on to find out why he's a "transitioning vegan" and why he'll happily wash your dishes.

So you live in a van, which is awesome. But how does that whole "kitchen thing" work out?

It's pretty straightforward. I have a two-burner propane stove, a bunch of cabinets, and a jug of water. It's just normal cooking. The whole kitchen is built into the side of the van. It's a flat countertop that also doubles as storage. There's a video of it online .

What's your go-to breakfast?

Right now I've mostly been doing granola, cereal-type stuff with almond milk and fruit. I pretty much alternate that with egg scrambles.

Almond milk: Are you dairy-free?

I'm not totally dairy-free, but I'm dairy-minimal.

What's your dream breakfast, then?

My fantasy breakfast is just a really good egg scramble. Maybe I'll add a little feta, so, uh, obviously not totally dairy-free. Definitely some vegetables, maybe some really nice tortillas; something to make it like a Mexican-style breakfast. I just really love breakfast.

What do you prefer: tacos or burritos?

Oh, burritos. They hold more inside, they hold together better.

It's been documented that you like cookies. Are you more a fan of cookies or cookie dough?

Cookie dough, for sure. I can live with other kinds of cookies, but chocolate chip is by far my favorite. I can make chocolate chip cookie dough off the top of my head; just by memory. It's the only thing I know how to bake, but I actually just eat the dough. I haven't done that quite in a long time.

If Half Dome was a food, what would it be?

I don't even know how to take that. The first thing that came to mind was a big lump of mashed potatoes, a pile of polenta or something. Or! Maybe a taco. It does have that kind of shape. Despite what you may see in pictures, it's actually taco-shaped. The south face is also vertical, although you never see it in photos. But it has two vertical sides.

Do you ever eat while you climb?

Yeah, you have to. I do light snacking the whole time, like two pieces of fruit, a bar, and a bunch of nuts. If you're climbing big routes that'll take you 16 hours, or like El Capitan , you have to take something like a big, robust sandwich. Climbing isn't like running or triathlons, where you have to constantly be eating blocks, gels, and pure sugar. Climbing is relatively slow, so you can pretty much eat anything and digest it as you climb.

Would you rather cook dinner for someone or be cooked for?

I'd much rather be cooked for. I hate cooking. I'm sort of a "do the dishes kind of guy."

You just put out your best personal ad, ever.

Yeah, that's perfect. If there are dish gloves, I'm a washer. I'm pretty anal about not getting my hands wet, because you have to keep your skin in good condition, and keep callouses for climbing.

What's the one food you'll never get sick of?

Red bell peppers. I love red bell peppers. Bell peppers in general, really. I like to eat them like apples. They're so crunchy and delicious.

Any foods you hate with a fiery passion?

Not really. I'll pretty much eat anything when the circumstances get dire enough. Although I don't like wasabi. That's something I'll probably never get into. There are some vegetables I don't really like, but because they're good for me, I'll eat them anyway.

Do you have a first food memory?

I do remember eating carrots out of our garden as a very little kid. And I still love carrots. It's funny; when I was younger, I didn't eat that many fruits and vegetables because I was much pickier. But now I look back at it, and think, "I can't believe I didn't like apricots. What was wrong with me?"

If you could ask the Bon Appétit Test Kitchen anything, what would it be?

If I could have a dialogue with them, I'd ask more about nutritional types of things. But I don't know if Bon Appétit really worries about nutrition too much [ Ed. note: we do ! ].

Any last words?

I make a fair amount of my food choices for environmental-type reasons than nutrition or taste. I'm trying to minimize impact, which is something most people don't necessarily think about when they're shopping. Which is why I'm partially vegetarian, trying to eat as little dairy as possible. I did just get home from Australia and had a couple kangaroo curries. And last year, I was in Namibia for a bit and I had some game meat-type stuff, mostly because I was frickin' starving and didn't have access to other food. I'm flexible about that stuff, but I'm trending vegan. I'm slowly easing that way.
