Serve the frittata warm or at room temperature, garnished with fresh herbs or a dollop of sour cream. It pairs beautifully with a simple green salad or fresh fruit for a light meal. For breakfast, serve alongside toast or pastries like Flaky Baking Powder Biscuits. This dish is perfect for brunch or a potluck.
