Cook the pasta according to the instructions on the package
In another pan, start with heating up the oil. When it’s nice and hot, add the finely sliced red onion and cook for 2 minutes.
Now add the frozen peas with the sliced zucchini (¼ of an inch slices) and cook for another 3 minutes.
Add the spinach and season with salt and pepper.
When the pasta is ready, rinse it and add it straight into the pan. Turn off the heat and add the pesto in and mix nicely until it coats all the pasta.
Serve with some sprinkled pine nuts on top and enjoy!
