Ingredients You’ll Need

- 4 large egg whites (or 1 cup liquid egg whites)
- 1 cup fresh spinach, roughly chopped (about 30 grams)
- 2 tablespoons low fat cottage cheese or low sodium ricotta, drained
Serves 1 to 2. Optional additions include a whole egg for richness, diced tomato, or 1 tablespoon low sodium shredded cheese for extra flavor.
Step-by-Step Recipe

- Preheat the oven to 350 F and lightly oil a 6-cup mini muffin tin or use a silicone tray. Sauté the diced onion in 1 teaspoon olive oil over low heat until soft, about 3 minutes, then add chopped spinach and cook 1 to 2 minutes until wilted. Remove from heat and cool slightly.
- In a bowl whisk the egg whites and the whole egg if using until blended. Stir in drained cottage cheese, the cooked spinach and onion, diced tomato if using, black pepper, and oregano. Fold in grated low sodium cheese if desired. Divide the mixture evenly among 4 to 6 mini cups, filling each about three quarters full.
- Bake for 15 to 18 minutes until tops are set and a toothpick comes out clean. For a softer texture remove when a little glossy in the center and let carryover heat finish cooking. Let rest 2 to 3 minutes then run a small knife around each cup and lift out. Serve warm or cool before storing.
