Preheat your oven to 375°F (190°C).
In a large mixing bowl, whisk together the eggs and milk until well combined.
Stir in the cheese and set the mixture aside.
In an ovenproof skillet, melt the margarine over medium heat.
Add the mixed vegetables to the skillet and sauté until they are tender, about 5 minutes.
Pour the egg mixture over the sautéed vegetables in the skillet.
Cook over medium heat for 4-5 minutes, or until the edges begin to set.
Transfer the skillet to the preheated oven and bake for 15-20 minutes, or until the frittata is set and lightly golden on top.
Remove from the oven, let it cool for a few minutes, then slice and serve.
