Layer
Spread pesto sauce evenly over the crust, followed by tomatoes in a single layer, red onion, and finally sprinkle 1/2 cup of the feta over entire pizza, saving 1/4 cup for later.
Broil
Place pizza in the oven on “broil” until feta is lightly golden, about 3-5 minutes depending on your oven. keep an eye on it!
Make Salad
In a medium mixing bowl, whisk together the olive oil, balsamic, salt & pepper. add the spring salad greens & toss lightly.
Top Pizza
Evenly pile salad on top of the pizza, sprinkle on the remaining 1/4 cup of feta. slice & serve!
