This pasta is low in calories and fat but is satifyingly filling. You can throw it together in minutes from a handful of ingredients, and unbelievably, it's looks very elegant.
Cook the pasta until al dente. Heat the olive oil in a pan, add garlic and sauté for 1 minute. Then add tuna, lightly mashed with a fork. Then stir in the rocket, season with salt and pepper, stir in lemon zest and juice.
Drain the pasta, add to the sauce, mix well together and serve immediately.
