1. Stir salt, pepper, and onion powder into ground beef, and form into a large patty by hand

2. Slice Halloumi into fourths width-wise, so you have four full-size thick slices

3. Heat a large pan over med-high heat until very hot

4. Place burger patty on one side of pan and cheese slices on other side; if pan isn’t nonstick, lightly oil burger side

5. Saute until cheese slices and patty are browned, flipping each once they’re browned

6. Timing will line up if you like burgers medium rare to medium; if you prefer them medium well or well, have oven preheated to 450 degrees and finish burger in oven for 4-5 minutes

7. Assemble as you would a normal hamburger, using the grilled cheese slices as the sandwich bun
