- Scottziki Sauce
- 1/2 cup plain yogurt
- 1/2 cucumber – peeled, seeded and finely chopped
- 1/2 teaspoon chopped fresh dill, or to taste
- Sandwiches
- 2 tablespoons olive oil
- 3 large cloves garlic, minced
- 1 large red onion, thinly sliced
- 1 pound ground beef
- 1 pinch dried oregano, or to taste
- 2 stalks celery, chopped
- 1 bunch fresh spinach, cleaned and stemmed
- 1/2 cup sliced fresh mushrooms (optional)
- 5 pita breads, warmed
- 1/2 cup banana pepper rings
- 2 tomatoes, cut into wedges
- Strain the yogurt in a yogurt strainer or coffee filter for 15 minutes. Mince the cucumber, and place into a mesh strainer to drain for 15 minutes. Squeeze any excess liquid from the cucumber, then place into a small mixing bowl. Stir in the yogurt and dill. Cover, and refrigerate until ready to serve.
- Heat the olive oil in a skillet over medium heat; stir in the garlic, and cook until fragrant, about 5 minutes. Set aside about 1/4 of the onion slices to use on the sandwiches, and add the remaining onion to the skillet; cook until soft, about 5 minutes more. Add the ground beef and oregano, and cook until the meat is no longer pink and is beginning to brown. Increase heat to medium-high, drain any grease from the beef, then stir in the celery, spinach, and mushrooms. Cook and stir until the celery has softened and the meat has nicely browned, about 5 minutes more.
- To assemble the Scyros, divide the meat among the warmed pitas. Top each sandwich with some onion slices, banana pepper rings, and tomato wedges. Dollop with the Scottziki sauce to serve.
