Nutrition per Serving

Ingredients

• 350 grams Beef ribeye or striploin (kept as a whole steak, surface completely patted dry with paper towels)
• 2 medium Bell peppers (red, yellow, green) (seeded and julienned)
• 1 medium Red onion (sliced thinly)
• 2 tablespoons Avocado oil (ideal for cast iron searing due to its 270°C (520°F) smoke point)
• 1.5 tablespoons Fajita spice complex (sugar-free; a blend of smoked paprika, cumin, garlic powder, and oregano)
• 2 tablespoons Fresh cilantro (Coriander leaves) (finely chopped, to support heavy metal detoxification)
• 1 whole Lime (cut in half)

Instructions

1. Remove all surface moisture from the steak using paper towels. Moisture prevents a proper sear and causes the meat to steam. Rub the meat with half of the fajita spice complex, salt, and pepper (dry rub). Let it temper at room temperature for 15 minutes.
2. Preheat a heavy cast-iron skillet over medium-high heat for at least 5 minutes. The thermodynamic heat retention ensures the pan's temperature won't drop when the meat hits it. Add 1 tablespoon of avocado oil; it should instantly shimmer and lightly smoke.
3. Lay the whole steak in the skillet and do not move it for 3-4 minutes. During this time, amino acids and sugars react (Maillard reaction) to create that legendary, flavorful brown crust. Sear the other side for 3 minutes, then transfer the meat to a cutting board.
4. In the same hot skillet, add the remaining avocado oil, sliced onions, and julienned peppers. Sprinkle with the remaining fajita spice. Flash-sauté over high heat for 4-5 minutes, scraping up the caramelized bits of meat stuck to the bottom (deglazing the fond).
5. The meat must rest for 5 minutes to allow the muscle fibers to relax and reabsorb their juices. Once rested, slice the steak into very thin strips strictly 'against the grain'. This mechanical technique ensures melt-in-your-mouth tenderness.
6. Build the bowl by laying down a bed of the sautéed peppers and onions. Top with the thinly sliced, juicy steak. Garnish with fresh cilantro leaves and a squeeze of fresh lime juice to balance the richness with bright acidity. Serve immediately.
