Instructions

    Cup of Yum
  1. Preheat the oven to 400F. Line a baking sheet with foil.
  2. Make the avocado salsa: In a bowl gently toss together the chopped avocado, finely diced jalapeno, minced basil, minced chives, juice of one lime, big pinch of salt and 1 tbsp olive oil. Set aside.
  3. To the baking sheet add the sliced peppers and sliced onion. Drizzle with 2 tbsp olive oil, 1 tsp salt, ½ tsp ground pepper, ¾ tsp garlic powder and ½ tsp onion powder and toss to coat everything well. Bake in the preheated oven for 12 minutes.
  4. While the vegetables are baking, prepare the steak by slicing into ½ inch pieces and seasoning with 2 tbsp olive oil, 1 1/2 tsp chili powder, ¼ tsp dried oregano, ½ tsp paprika, 1 ½ tsp ground cumin, ¼ tsp garlic powder, ¼ tsp onion powder, 1 tsp salt, ½ tsp ground pepper.
  5. After the vegetables have baked for 12 minutes, remove the sheet pan from the oven.
  6. Make space in the center of the sheet pan and add the sliced and seasoned steak. Bake for 5 minutes and then remove from the oven.
  7. Add a few ‘piles’ of shredded monterey jack cheese to the pan and bake for 3 more minutes. Remove from the oven.
  8. Squeeze lime wedges over top of the steak and vegetables before serving with fajitas and topped with avocado salsa, sour cream, tomato salsa (optional), cilantro, jalapenos and melty cheese from the sheet pan.

Notes

  • We love making this into classic fajitas but you could also serve with a side of rice and beans instead.
  • If you want to add different vegetables, swap out a pepper for zucchini and/or mushrooms.
