Bring a large pot of water to a boil, salt generously and cook pasta according to package instructions.
Meanwhile, in a large skillet heat olive oil and sauté onion for 3-4 minutes. Add frozen peas and a pinch of salt and cook, stirring, for 2 minutes.
Stir in tuna, breaking up the chunks with your wooden spoon. Add cooking cream and lemon zest. Add salt and pepper, to taste. Bring the sauce to a simmer.
Drain pasta and stir into the tuna mixture. Garnish with freshly chopped parsley and serve hot.
Notes
When possible, opt for light chunk tuna packed in water for this recipe.
Use any medium length pasta of your choice including (but not exclusively) penne rigate, rigatoni, fusilli; gemelli or cavatappi.
As a general rule, I prefer frozen over canned peas for their bright green color and texture over softer canned peas. However, in a pinch canned peas will do.
Refrigerate leftovers for up to 3 days.
Contrary to popular belief that cheese and fish do not go well together, a light sprinkling of Parmesan cheese when serving this pasta is delicious!
