Start by boiling water for the pasta in a big pot and then pour the spaghetti in it, when the water is ready.
Then on a pan pour 2 table spoons of olive oil and cook the chili peppers and then after 2 minutes add the shrimps and then the basil leaves. When the shrimps are cooked well and they are soft, place them on a big bowl, without throwing away the oil, that they were cooked in.
If the pasta is done, pass it through a colander and pour it in the bowl with the shrimps and mix well. Serve the food and optionally decorate the plates with paprika, like in the picture.
