1 tablespoon plus 2 teaspoons olive oil
1 medium red onion, sliced in to strips
2 cloves garlic, minced
1 medium red bell pepper, cut into strips
1 pound beef sirloin tip steak, cut into thin strips (grass-fed beef recommended)
4 ounces white mushrooms, sliced
2 teaspoons dried oregano
1/2 teaspoon black pepper
Salt to taste
2 whole wheat pita pockets cut in half
4 leaves of Romaine lettuce, torn into small pieces
1/4 cup Greek yogurt, fat free, plain (optional fat free sour cream)
Preheat oven to 350 degrees.
In a large skillet, on medium-low heat, sauté mushrooms in 1 tablespoon olive oil, about 6 minutes. Add onions, garlic and bell peppers and continue sautéing until onions and peppers are tender, about 4 minutes minutes.
Add in sirloin strips, and cook on medium heat for about 5-10 minutes or until no longer pink. Sprinkle with salt and pepper and oregano. Stir well, cover and simmer for 5 more minutes. Drain mixture.
Cut pita bread in half, brush remaining oil on all sides, place on a cookie sheet for 3-5 minutes, just long enough to warm. Stuff pita pockets with meat mixture, romaine lettuce and top with a dollop of yogurt or sour cream.
