Instructions:

1. Preheat Oven:
Preheat your oven to 375°F (190°C). Grease a pie dish or quiche dish with a bit of olive oil.
2. Prepare Vegetables:
- Heat 1 tbsp of olive oil in a large skillet over medium heat.
- Add the finely chopped onion and cook until it becomes translucent, about 5-6 minutes.
- Add the minced garlic and sauté for another 1-2 minutes until fragrant.
3. Cook Mushrooms and Broccolini:
- Add the sliced mushrooms to the skillet and cook until they release their moisture and start to brown, about 8-10 minutes.
- Stir in the broccolini pieces and cook for another 5 minutes, until they are tender but still bright green.
- Season with salt and pepper to taste, then remove the skillet from heat.
4. Prepare Egg Mixture:
- In a medium bowl, whisk together the 4 egg whites until slightly frothy.
- Stir in the shredded cheddar cheese and 1 tbsp of the grated Parmesan cheese.
5. Combine and Assemble:
- Spread the cooked vegetables evenly over the bottom of the prepared pie or quiche dish.
- Pour the egg and cheese mixture over the vegetables, making sure it spreads evenly.
- Sprinkle the remaining 1 tbsp of grated Parmesan cheese on top.
6. Bake:
- Place the dish in the preheated oven and bake for 25-30 minutes, or until the quiche is set and the top is lightly golden.
- Check by inserting a knife or toothpick into the center; it should come out clean.
7. Cool and Serve:
- Allow the quiche to cool for a few minutes before slicing.
- Serve warm or at room temperature.
