Pasta salad with tuna and vegetables

Bring a large pot of water and salt to a boil. When the water boils, add the penne pasta and cook according to package instructions (approximately 15-16 minutes), until al dente.

While the pasta is cooking, prepare the vegetables: cut the cucumber and bell pepper into cubes, and the cherry tomatoes in half. Drain the tuna from its own juice.

In a large bowl, mix the chopped vegetables, drained tuna, plain yogurt, and mayonnaise. Season with salt and pepper to taste.
