Prepare the pasta according to the instructions on the package. Cook for 1 minute less than instructions ask for. Once cooked drain immediately and let cool.
In a small bowl whisk together all of the dressing ingredients and set aside.
Once pasta has cooled place it in a large bowl and add the tuna, tomatoes, cucumbers, red onion, and fresh parsley. Toss together.
Pour the dressing over the salad and toss until everything is well coated.
Serve immediately or store in the refrigerator until ready to serve.
Notes
We used three pastas: Fsilli Chickpea Pasta, Fusilli Green Lentil Pasta, and Penne Red Lentil Pasta to make up our 8 ounces of pasta.
