It's hard to deny the nutrients of kale—the dark leafy green is filled with fiber, vitamins K, A, and C, plus cancer-fighting antioxidants—so it was truly only a matter of time before the tasty veggie was more widely available.

And now, that time has come.

Today, Starbucks announced that it will offer three Evolution Fresh smoothies on its menu, with super-veggie kale as an optional addition.

And it's not the only on-the-go restaurant that's understood the power of kale: Rumor has it that McDonald's will also soon offer kale as an ingredient in salads or smoothies (maybe both?).

I'm down with the idea! What do you think?
