- b.In a small bowl, whisk together the chili powder, ground cumin, smoked paprika, garlic powder, dried oregano, salt, and black pepper to create the fajita seasoning.

Step 2
- a.Sear the Steak
- b.Heat 1.5 tablespoons of canola oil in a large cast-iron skillet or heavy-bottomed pan over medium-high heat until it shimmers.
- c.Carefully add the steak to the hot pan in a single layer, working in batches if necessary to avoid overcrowding. This ensures a good sear rather than steaming the meat.
- d.Cook for 2-3 minutes per side until well-browned and cooked through. Remove the steak from the skillet and set aside on a plate.

Step 5
- a.Assemble and Cook the Quesadillas
- b.Wipe the skillet clean or use a separate large non-stick pan over medium heat. Place one tortilla flat in the pan.
- c.Sprinkle about 1/4 cup of shredded cheese over one half of the tortilla.
- d.Evenly distribute one-quarter of the steak and vegetable filling over the cheese.
- e.Top the filling with another 1/4 cup of cheese. Fold the empty half of the tortilla over the filling.
- f.Cook for 2-4 minutes per side, pressing down gently with a spatula, until the tortilla is golden-brown and crispy, and the cheese is completely melted.
- g.Repeat with the remaining tortillas and filling.

Step 6
- a.Rest and Serve
- b.Transfer the cooked quesadilla to a cutting board and let it rest for a minute. This helps the cheese set and prevents the filling from spilling out when cut.
- c.Slice into wedges and serve immediately with your favorite toppings like sour cream, salsa, guacamole, or fresh cilantro.
What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1For the most tender steak, slice it thinly against the grain. Freezing the steak for 15-20 minutes can make it easier to slice.
- 2Use a cast-iron skillet for the best sear on the steak and a nice char on the vegetables.
- 3Don't overcrowd the pan when cooking the steak. Searing in batches ensures a crispy, brown crust.
- 4Shred your own cheese from a block. Pre-shredded cheeses contain anti-caking agents that can prevent them from melting smoothly.
- 5Warm the tortillas in the microwave for 15-20 seconds before assembling. This makes them more pliable and less likely to tear when folded.

Why this is on our healthy list.
Excellent Source of Protein
The flank steak provides high-quality protein, which is essential for building and repairing tissues, supporting muscle mass, and maintaining overall body function.
Rich in Iron
Beef is a prime source of heme iron, a type of iron that is more easily absorbed by the body than non-heme iron from plants. Iron is crucial for preventing anemia and transporting oxygen in the blood.
Packed with B Vitamins
Steak is a powerhouse of B vitamins, particularly B12 and B6. These vitamins are vital for energy metabolism, brain function, and the formation of red blood cells.
Vitamin C Boost
Bell peppers, especially red ones, are loaded with Vitamin C, a powerful antioxidant that supports the immune system, promotes healthy skin, and aids in iron absorption.
