Oven Baked Beef Fajitas.

High-strung fajita purists, look away now, because this recipe is about to get creative. Instead of being grilled or pan-seared, this version is baked in the oven, with the meat and the vegetables all together. It only takes a couple minutes on each side before everything’s ready to load into your choice of lettuce wrap or cauliflower tortillas (or to just eat plain with salsa or whatever other toppings you like).

This is a great trick to have up your sleeve for a night when you want something now and don’t have a lot of options. It’s basically roasted meat and vegetables, but the spices tie it all together and it’s a seasoning combination that kids will love.

If you have anything left over, this would also be good cold for a lunchbox the next day (with or without any kind of wrap). It’s already cut into conveniently-sized pieces for forking right into your mouth!
