Creating your Spring Vegetable Frittata is straightforward. Follow these easy steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Sauté the Vegetables: In an oven-safe skillet, heat olive oil over medium heat. Add onions and garlic, cooking until soft. Add zucchini and bell peppers, sautéing for another 5 minutes. Finally, stir in the spinach and cook until wilted.
3. Whisk the Eggs: In a bowl, whisk together the eggs, milk, salt, and black pepper until well combined.
4. Combine Ingredients: Pour the egg mixture over the sautéed vegetables in the skillet. Gently stir to distribute the veggies evenly.
5. Add Cherry Tomatoes and Cheese: Scatter the halved cherry tomatoes and grated cheese over the top of the mixture.
6. Cook on the Stove: Cook the frittata on the stovetop for about 2-3 minutes or until the edges begin to set.
7. Transfer to Oven: Place the skillet in the preheated oven to finish cooking for 10-15 minutes or until the frittata is set and golden.
8. Cool Slightly: Once baked, remove from the oven and let it cool for a few minutes.
9. Slice and Serve: Cut into wedges and garnish with fresh herbs if desired.

With these simple steps, you’ll have a flavorful frittata ready for any meal!
