This is an example of a simple pasta I threw together for lunch. To make it, I cooked two cloves of minced garlic in olive oil while bringing the pasta water to a boil. I added thinly sliced courgette/zucchini and salt to the pan and cooked the vegetable while the pasta cooked. After draining the pasta, I added it to the frying pan along with black pepper and juice of half a small lemon.
A similar dish could be made from any other vegetables. The picture below shows the same dish with broccoli and dried chilli flakes. In this case I cooked the broccoli together with the pasta, albeit for only half as long.
