Let’s start preparing all vegetables.
Halve the peppers, discard the stalks and seeds and slice them lengthways into strips, then in 3 cm pieces.
Cut the eggplant into 1,5 cubes and quarter the cherry tomatoes.
Peel the onion and finely slice. Heat the oil in a large skillet and fry the garlic over a medium heat. Cook it until softened and golden, stirring occasionally with a wooden spoon.
Add the eggplants and peppers, and season with salt. Continue cooking over medium-high heat for 5 minutes, stirring and loosen it up with some tablespoons of warm water, if needed. Tip into the tomatoes, cover and cook for further 30 minutes over a low heat. Add some red chilli pepper flakes if you like it.
Mince the fresh parsley together with basil leaves and capers, cut the olives, then add everything into the vegetables sauce and cook for a few minutes.
Meanwhile, cook the pasta in a large saucepan of boiling salted water until al dente.
Drain the Pennette al dente, reserving some cooking water. Tip into the skillet, together with the vegetables and toss everything until combine, adding some cooking water, if needed.
Finely serve your delicious Pennette with some basil leaves on top.
