This quick and easy recipe is great served warm for dinner with crusty bread or cold as a pasta salad. Perfect for lunch, road trips, or an elegant meal at home.
If using homemade pesto, all all ingredients to a food processor and blend till combined, seed particles should be even and small. Meanwhile bring a large pot of salted water to a boil and add pasta. Cook according to package directions, then drain, reserving about 1/4 to 1/2 cup of the pasta water.
In a large bowl, combine pesto and tuna. Stir in warm pasta, and 1/4 cup of the pasta water, till everything is fully coated with the tuna and pesto sauce. Taste and adjust any seasonings. Serve warm or cover and refrigerate to serve as a pasta salad.
Notes
For a more "saucy" pasta, add more pasta water as desired, about 1 tablespoon at a time.
Basil turns black with a lot of heat. It should be fine with the pasta and a little bit of water, but be mindful when reheating. Especially in the microwave. This is also why we toss the pesto in a bowl rather than on the stove.
To preserve the flavor and color, I recommend serving leftovers cold or at room temperature.
