chop half of a large eggplant or a small one
chop 1/2 of yellow onion
chop 2 cloves of garlic
2 table spoons of tomato paste
1/2 cup of pasta cooking water
olive oil, salt and pepper to taste

Saute the onions till translucent for a few minutes, add the garlic
add the peppers and cook for 2 minutes
add the eggplant and tomato paste
add some of the liquid from pasta
add 1 cup of the pesto
