Preheat your oven to 375°F (190°C).

In a large skillet, heat olive oil over medium heat. Add zucchini, bell peppers, and cauliflower, cooking until golden.

Stir in the spinach, cooking until wilted. Season with thyme and oregano.

In a mixing bowl, whisk eggs and then combine with sautéed vegetables and cheese.

Grease a casserole dish, pour in the mixture, and top with more cheese if desired.

Bake for 25-30 minutes until golden and bubbly.

Let cool for 5-10 minutes before serving.
