Ingredients

1 lb flank steak, sliced
1 bell pepper, sliced
1 onion, sliced
2 tablespoons olive oil
1 teaspoon chili powder
1 teaspoon cumin
Salt and pepper to taste
Tortillas for serving
Optional toppings: avocado, salsa, cheese, sour cream

Short substitution tips: Swap flank steak for chicken or tofu if you prefer. Add mushrooms, zucchini, or any other favorite veggies for extra nutrition!

Step-by-Step Instructions

Preheat the oven to 400°F (200°C).
In a large bowl, toss the sliced flank steak, bell pepper, and onion with olive oil, chili powder, cumin, salt, and pepper.
Spread the mixture on a sheet pan in a single layer.
Bake for 20-25 minutes, or until the beef is cooked through and the vegetables are tender.
Serve in warm tortillas with your choice of toppings.

Visual doneness cues: Look for browned meat and tender veggies.
Texture tips: The steak should be juicy, while the peppers and onions have a slight char.
Common mistakes to avoid: Don’t overcrowd the pan; it leads to steaming instead of roasting—trust me on this one!

And yes, it can get a little messy when you’re assembling your fajitas. But that’s the fun of it, right?
