1) Place pasta water on to boil. Salt water then add pasta and cook to al dente.
2) While pasta cooks, heat a deep skillet over medium heat with extra-virgin olive oil. Saute garlic and onions until tender, 4 to 5 minutes. Add tuna and sun-dried tomatoes and stir to heat through, another 1 to 2 minutes. Add wine and cook it down a minute then add cream and season sauce with salt and pepper. Toss hot pasta and peas with sauce and cheese.
Serve pasta on dinner plates and top with shredded basil.
