Instructions

1. 1Combine the olive oil, fresh lime juice, minced garlic, ground cumin, brown sugar, and red pepper flakes in a bowl. Divide the marinade in half—place the flank steak in one portion and marinate for at least 30 minutes at room temperature (or up to 2 hours refrigerated). Reserve the other half of the marinade untouched for cooking and serving.
2. 2Heat olive oil in a cast iron skillet or grill pan over medium-high heat until shimmering. Remove the steak from its marinade and place in the hot pan. Cook 4–5 minutes per side over medium-high heat until deeply browned and the internal temperature reaches 130–135°F for medium-rare. Transfer to a cutting board and rest for 5 minutes.
3. 3Wipe the pan clean with a paper towel and add olive oil over medium-high heat. Add the sliced bell peppers and onions in a single layer. Cook 5–7 minutes over medium-high heat, stirring occasionally, until tender-crisp and lightly charred at the edges. Pour half of the reserved marinade over the vegetables and cook 1–2 minutes more until the liquid reduces slightly.
4. 4Slice the rested steak thinly against the grain.
5. 5Warm the flour tortillas in the same skillet over medium heat, 30 seconds per side, until pliable and lightly toasted.
6. 6Divide the sliced steak, sautéed peppers and onions, raw romaine lettuce, sliced avocado, and fresh cilantro evenly among 4 airtight containers while warm.
7. 7Store the remaining reserved marinade separately in a small container for drizzling at serving time.
8. 8Top each portion with sour cream and drizzle with the reserved marinade when ready to eat. Serve with warm tortillas.
