Equipment

  • Mixing bowls
  • Cast iron skillet or grill pan
  • Knife and cutting board
  • Tongs or spatula
  • Meal prep containers (optional)

Ingredients
  

Steak & Marinade

  • 1 ½ lbs flank, skirt, or sirloin steak
  • Juice of 2 limes
  • 3 tbsp olive oil
  • 3 garlic cloves (minced)
  • 1 tsp chili powder
  • 1 tsp cumin
  • ½ tsp smoked paprika
  • Salt & pepper to taste

Vegetables

  • 2 bell peppers (sliced)
  • 1 large onion (sliced)
  • 1 tbsp olive oil

Toppings/Base

  • 2 cups cauliflower rice or lettuce
  • 1 avocado (sliced)
  • 1 cup pico de gallo or salsa
  • ½ cup shredded cheese (optional)
  • ½ cup sour cream or Greek yogurt
  • Fresh cilantro for garnish

Instructions
 

  • Marinate Steak: Mix lime juice, olive oil, garlic, and spices. Coat steak and refrigerate for 30 minutes or overnight.
  • Cook Steak: Heat skillet over high heat. Sear steak 4–5 minutes per side until charred and medium-rare. Rest 5–10 minutes, then slice against the grain.
  • Sauté Veggies: In the same skillet, cook peppers and onions until tender-crisp, about 5–7 minutes.
  • Assemble Bowls: Place cauliflower rice or lettuce in bowls. Top with steak, peppers, onions, and chosen toppings.
  • Serve Immediately: Enjoy hot for best flavor and texture.

Notes

  • Pro Tip: Rest steak before slicing to keep juices locked in.
  • Variations: Try chipotle marinade, add guacamole, or swap steak for portobello mushrooms.
  • Storage: Steak and veggies keep 3–4 days refrigerated. Assemble fresh for best texture.
  • Meal Prep Friendly: Store components separately in containers for easy weekday lunches.
