01 - Preheat oven to 375°F (190°C). Position rack in the center of the oven.
02 - Heat olive oil in a large ovenproof skillet over medium heat. Add asparagus, zucchini, and scallions. Sauté for 3–4 minutes until just tender but still vibrant.
03 - Stir in the baby spinach and thawed peas. Cook for 1–2 minutes until the spinach is fully wilted. Remove from heat.
04 - In a mixing bowl, whisk together the eggs, milk, salt, pepper, and thyme until smooth and well combined.
05 - Spread the sautéed vegetables evenly across the bottom of the skillet. Pour the egg mixture over the vegetables. Gently shake the skillet to ensure even distribution.
06 - Scatter the crumbled goat cheese evenly over the surface of the egg mixture.
07 - Return the skillet to low-medium heat and cook without stirring for 3–4 minutes, just until the edges begin to set and pull away slightly from the sides.
08 - Transfer the skillet to the preheated oven. Bake for 12–15 minutes until the center is fully set and the top is lightly golden.
09 - Remove from the oven and allow to cool slightly before slicing into wedges. Serve warm or at room temperature.
