Put a large pan of water on the stove to boil; once it boils, salt it and cook your pasta in it following instructions on the package regarding the time.
Meanwhile, wash your zucchini, remove the top and bottom and chop them in bite-sized chunks; try to keep the zucchini bite size, avoiding pieces bigger than the pasta, as you want the lemon zucchini pasta sauce to mix well with the pasta.
In a frying pan, add the olive oil and warm up. Once this is warm, add the zucchini to the pan and mix well.
Allow the zucchini to golden on a medium-low flame, and after 8-10 minutes they will be ready.
Once the zucchini are ready, dress them with half the lemon juice.
Once the pasta is ready and the zucchini are cooked (they can have a bit of a bite to them), drain the pasta from the water and add it to the pan with the zucchini. Dress it with the lemon juice, salt and pepper.
Just before serving, add the crumbled feta, mix well and serve. Enjoy!
