# How To Make It:
01 - Combine olive oil, lime juice, garlic, cumin, smoked paprika, chili powder, salt, and black pepper in a bowl. Add the sliced beef and toss to coat thoroughly. Marinate for at least 15 minutes, or refrigerate up to 2 hours for deeper flavor penetration.
02 - Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add the sliced peppers and red onion. Sauté for 4–5 minutes until softened and slightly charred at the edges. Remove from skillet and set aside on a plate.
03 - In the same skillet, arrange the marinated beef in a single layer. Cook for 2–3 minutes per side until well-browned and just cooked through. Return the sautéed vegetables to the skillet, toss everything together, and cook for 1 additional minute. Remove from heat immediately.
04 - Mash the avocados in a bowl until mostly smooth with some chunks remaining. Stir in the diced tomato, chopped onion, lime juice, cilantro, salt, and pepper until well combined. Adjust seasoning to taste if needed.
05 - Warm the tortillas in a dry skillet or microwave until pliable. Fill each tortilla with the beef and vegetable mixture. Top generously with guacamole. Garnish with fresh cilantro or a dollop of sour cream if desired. Serve immediately with lime wedges on the side.
