Cheesy Cheddar and Spinach Frittata

This cheesy cheddar and spinach frittata is the ultimate clean-out-the-fridge meal that somehow always feels intentional. Toss in a handful of greens—baby spinach, kale or arugula all work (just give sturdier greens a quick sauté first)—and use up any odds and ends of cheese. If you have extra herbs on hand, even better: Parsley, cilantro, and basil are all great here. It’s endlessly adaptable, low-effort and just as good for a quick weeknight dinner as it is for a lazy weekend brunch. Bonus: leftovers taste great warm or at room temperature, making it perfect for meal prep.
