Colorful Quiche

Got leftover vegetables? Great!

Turn them into a cheesy egg pie with a caramelized onion crust. This colorful quiche is a great way to use up leftover vegetables while adding more vitamins, minerals, and fiber to your day. The eggs and cheese provide protein to help keep you full and energized, while the vegetables add nutrients that support heart and digestive health. It’s an easy, budget-friendly meal that tastes as good as it is good for you!

There are two ways to make this quiche.

If you have a cast-iron or other oven-proof skillet, you can make the quiche right in the skillet to cut down on dishes. Otherwise, start with a regular skillet and later transfer everything to a pie dish to bake.

Ingredients

Servings: 4

1 tablespoon butter
1 large onion, sliced into half moons
3-4 cups chopped vegetables – choose your favorites!
8 large eggs
1 cup milk
1 cup cheddar cheese, grated
1 teaspoons salt
1/2 teaspoons black pepper

Tip!

Steam or cook vegetables like broccoli, cauliflower or winter squash before adding to the quiche to make sure they’ll be fully cooked. Any other quick-cooking vegetables, like tomatoes, zucchini, or spinach can just be used fresh – no need to pre-cook.
