Season the steaks with 2 teaspoons salt and pepper on all sides. Allow to rest at room temperature for 10 minutes.

Heat 2 tablespoons avocado oil in a large, heavy-bottomed skillet over medium-high heat. Sear steaks for 2 minutes per side until a golden crust forms. Work in batches if needed to avoid overcrowding. Transfer to a plate and loosely cover.

Add remaining tablespoon of avocado oil to the same pan. Add onions and bell peppers, season with 1 teaspoon salt, and sauté until softened and slightly caramelized, about 5 minutes, stirring frequently.

Stir in the sliced garlic and cook for 15 seconds until fragrant, being careful not to brown.

Pour in the white wine, vigorously scraping up any browned bits from the bottom of the pan. Allow the wine to reduce until almost evaporated, about 30 seconds.

Add crushed tomatoes, olives, and capers. Stir to combine thoroughly. Bring the mixture to a gentle boil, then immediately reduce to a simmer.

Return steaks to the pan, nestling them into the sauce. Cook for 3 minutes, then flip and cook for an additional 2 minutes for medium-rare doneness (internal temperature of 130-135°F).
08 -
Transfer the steaks to a serving platter, pouring the sauce generously over and around them. Serve immediately with crusty bread, pasta, or a light salad.
