How To Make Low FODMAP Steak Fajitas:
Sear the Steak:
Heat ½ tbsp of garlic-infused olive oil in a large skillet over medium-high heat. Add the steak and cook, stirring, until browned and cooked through. Remove from pan and set aside.
Sauté the Vegetables:
Add the remaining ½ tbsp of garlic-infused oil to the pan. Stir in the red bell peppers, leek greens, and tomatoes. Cook for 4–5 minutes until vegetables soften.
Add Spices and Simmer:
In a small cup, mix cumin, chili powder, oregano, cayenne pepper, and ¼ cup water. Pour into the pan with the veggies. Return steak to the pan and stir until sauce thickens and water evaporates.
Serve:
Spoon over warm white rice. Garnish with chives or fresh herbs if desired.
