These easy spring vegetable frittata muffins with Gruyere cheese are perfectly portioned, fluffy, and packed with fresh flavors, making them ideal for quick breakfasts or easy lunches.
Sauté the vegetables first to reduce moisture and enhance flavor. Do not overfill muffin cups; fill about ¾ full. Tent with foil if tops brown too quickly. Pat veggies dry if watery. Muffins freeze well for up to 2 months.
