Step 1: – boil the pasta until "al dente" (cooked through).
Step 2: – once pasta is boiled add the jar of pasta sauce, tuna and onion and stir so it all heats through.
Step 3: – add the garlic and herbs (i don’t measure i just do it to taste).
Step 4: – mix everything through and serve.
Step 5: -grate parmesan cheese on top with a little salt and pepper to season.
Step 7: simple as that!!! ^_^
