The Perfect Occasion for This Recipe
This is not for a dinner party. This is for the night you walked in the door at 7:15, the kids are hangry, and you haven’t eaten since lunch. It’s for the post‑gym “I need protein now or I’ll eat the couch” moment. It’s for a Wednesday that feels like a Monday. No fancy plating. No garnishes you’ll pick off. Just food on a tortilla. Use pre‑sliced peppers from the store. Don’t peel the garlic — crush it. Frozen onions? Go for it. The oven does the work.

Frequently Asked Questions
Can I use frozen peppers and onions?
Yes. Dump them frozen straight onto the sheet. Add two extra minutes to the bake time. Done.
What if I don’t have every spice?
Use chili powder + cumin plus anything else you’ve got. It will still taste good. Don’t overthink spices.
Can I make these vegetarian?
Swap chicken for a can of black beans (drained) or extra peppers. No changes to time.
Do I have to use corn tortillas?
Nope. Flour, whole wheat, even lettuce wraps. Whatever you have. Just warm them.
How do I reheat leftovers?
Sheet pan at 350°F for 5 minutes. Or microwave. Either way, eat fast.
