Packed with spinach, mushrooms, and egg whites, they're the perfect blend of protein and vegetables. This recipe is not only easy to make but also versatile and can fit into various dietary preferences.

Instructions:

1. Preheat the Oven:
Preheat your oven to 375°F (190°C).
2. Prepare the Bell Peppers:
- Slice off the tops of the red peppers and remove the seeds and membranes.
- Lightly brush the outsides with a tiny bit of olive oil. Set them aside.
3. Sauté the Vegetables:
- Heat 1/2 tsp of olive oil in a large skillet over medium heat.
- Add the finely chopped onion and cook for about 3-4 minutes until it starts to become translucent.
- Add the mushrooms to the skillet and sauté for another 5 minutes until they release their moisture and start to brown.
- Stir in the roughly chopped spinach and cook until wilted, about 2-3 minutes.
- Season the mixture with a dash of salt. Mix well and remove from heat.
4. Fill the Peppers:
- Evenly distribute the sautéed vegetable mixture among the hollowed red peppers.
- Carefully pour the egg whites into each pepper, filling them almost to the top. The egg whites will expand slightly while cooking.
5. Bake the Peppers:
- Place the filled peppers upright in a baking dish. If they don’t stand upright, you can use crumpled aluminum foil to help stabilize them.
- Bake in the preheated oven for 25-30 minutes, or until the egg whites are set and the peppers are slightly tender.
6. Serve:
- Remove from the oven and let them cool slightly before serving.
- Optional: Garnish with fresh herbs, a sprinkle of cheese, or a dash of hot sauce for extra flavor.
