Editor's note: Each Saturday morning we bring you a Sunday Brunch recipe. Why on Saturday? So you have time to shop and prepare for tomorrow.
Earthy, soft spinach and salty brined feta are a classic Greek combination that work together in pretty much any dish—and the frittata is no exception. Plus it's a great, simple dish that feeds a lot of people, and gets you a big portion of your daily vegetable intake. Any leftovers slapped between two nice pieces of bread will make for a great brown bag lunch Monday morning.
Wilting fresh baby spinach is your best option, but in a pinch, that block of spinach in your freezer will work too. Just be sure to defrost it in the fridge overnight, or in the microwave a few minutes at a time.
