Warm whole wheat pasta salad with tuna and green beans

Trim the green beans and cut them in half. Halve the cherry tomatoes and thinly slice the half red onion.

Fill the saucepan with 2 L of water, add the pinch of salt and bring to a full boil over high heat.

Drop the green beans into the boiling water and cook for 5 min: they should stay a little crunchy. Lift them out with a slotted spoon or drain them in the colander while keeping the water in the saucepan, then put them in the mixing bowl.

Bring the water back to a boil, then add the 250 g of whole wheat pasta and cook for 10 to 11 min, stirring now and then. Drain well.

While the pasta cooks, heat half the olive oil in the skillet over medium heat and sauté the red onion for 3 min until it softens.

Open the 2 cans of tuna, drain them well and flake the tuna with a fork or spoon.

Tip the warm pasta into the mixing bowl with the green beans, onion, cherry tomatoes and tuna. Add the rest of the olive oil, the balsamic vinegar and the pepper, then toss gently.
