I often cook pasta like you as well. It's easy to make! All you need are 3 minutes to throw everything in a pot with water
Sometimes, all you need is to boil it and then add some "special sauce" on top. You can buy it at the supermarket, tomato sauce with meat, mushrooms, vegetables.... you name it! All you need to do is open the jar
However, like you said, pasta has way to many calories! So, I found an interesting solution to this problem
My favorite pasta dishes (that I make myself) are pasta with veggies. I simply replace some pasta by adding veggies.
The combinations I like most are pasta with broccoli or with zucchini.
You simply boil the pasta (less than usual, a handful of pasta is enough) and, separately, you cook the veggies. If it's broccoli, boil them first for a few minutes, then stir fry them in a pan with some garlic and olive oil. If it's zucchini, I grate them directly in a pan and stir fry them with garlic and olive oil.
Add the boiled pasta in your pan, mix everything and, for one last touch, add some grated cheese to the "mixture".
It's yummy and it definitely has less calories
