Ingredients
Method
- Preheat oven to 400°F. Line a large rimmed baking sheet with parchment paper or a Silpat mat and set aside.
- Combine the sliced flank steak, peppers, and red onion in a large mixing bowl. Drizzle with olive oil and add the cumin, chili powder, cayenne, and red pepper flakes. Season generously with salt and black pepper and toss until everything is evenly coated.
- Spread the steak and vegetable mixture onto the prepared baking sheet in a single layer. Don’t overcrowd. Use a three-quarter sheet pan if you have one, or roast in two batches if needed.
- Roast for 15–20 minutes, until the steak is cooked to your liking and the peppers are soft and slightly caramelized at the edges.
- Remove from the oven and immediately squeeze fresh lime juice over everything. Scatter with fresh cilantro and serve with diced avocado and warm corn tortillas or lettuce wraps.
Notes
For extra flavor, toss the steak with the olive oil and spices up to 24 hours ahead and refrigerate until ready to cook. The longer it marinates, the better it gets.
