Pasta on the fly

I'm trying to force myself to rely on my own knowledge and "gut feeling" for recipes. I frequently use other people's recipes, and this year I'm going to try and create some of my own. Here is one attempt (although I did draw inspiration from the Lemony Tuna Pasta recipe): I didn't include any measurements in this recipe as I really just eyeballed everything and put in the amount that sounded good to me. You really can't go wrong with this recipe, and you can substitute any ingredients that you like.

Ingredients:Peas
Broccoli

Feta cheese
