Cube the Beef
Cut 1 kg of beef strips into small, even cubes. This helps the meat cook faster and stay juicy.
Time: PT7M
Clean Cutting Board
Wash your cutting board and knife thoroughly with hot, soapy water after cutting raw beef to avoid cross-contamination.
Time: PT2M
Prep Bell Peppers
Remove seeds from mini bell peppers (or 2 large bell peppers) by smacking or tapping them, then slice into thin, even strips.

Prep Sweet Potatoes
Wash 1 kg sweet potatoes, peel if desired, and cut into 1-inch cubes.

Season and Cook Sweet Potatoes (Air Fryer or Oven)
Toss sweet potato cubes with 1 tbsp olive oil, 1 tsp garlic powder, 1 tsp paprika, and a pinch of salt. Air fry at 400°F (205°C) for 20 minutes, shaking halfway. Alternatively, bake in oven at 400°F (205°C) for 25-30 minutes, stirring once.
Time: PT20M

Brown the Beef
Heat a skillet over medium heat. Add a spray or drizzle of oil. Add beef cubes and brown for 5-6 minutes, stirring occasionally.

Once browned, sprinkle 1 tbsp fajita seasoning over beef and toss to coat. Remove beef from pan and set aside.

Sauté Peppers, Onion, and Garlic
In the same pan, add peppers, onions, and 2 crushed garlic cloves. Add another 1 tbsp fajita seasoning and a pinch of salt. Sauté over medium heat for 6-8 minutes until veggies are softened but still have some crunch.
