Asparagus, Tomato, and Spinach Frittata

I loved the Margherita Frittata so much that I made another frittata this week. I envisioned a veggie frittata with feta cheese but realized that I was out of feta. I used up the last of my asparagus and baby spinach that I had in the refrigerator and threw in a handful of cherry tomatoes. It was wonderful without the feta but I will add it next time because I love the salty and creamy flavor it
