favorite recipe (sales/pastas) using a jar of Italian Tuna (no tomato based sauces) thanks?

First Night in Florence, hands down.

Here's a new take on the classic Tuna Salad. Added chickpeas and apple make it a refreshing alternative to the typical mayo-heavy variety: http://www.healthline.com/health-recipes/tuna-salad

My quick and easy go-to (which also works very well with smoked, wild Alaskan, canned salmon) is linguine with a lemon butter sauce (1 lemon per 1-2 tbsp. butter) and chives, topped with a bit of parm if you like.

I love a good riff on a salad nicoise. Lots of good recipes on the internet.

Madhut Jaffrey has a lovely tuna curry in one of her Quick Indian cookbooks. Weeknight meal.

Make a curried tuna sauce for pasta. This is a recipe from a Silician chef. Melt a stick of unsalted butter. Add red chile flakes and a generous spoon of mild curry powder. Cook on med heat for about a minute. Add tuna with the oil. Break up tuna with a fork. Remove from heat and add hot cooked long pasta. Toss well and serve immediately.

Well, I would have suggested First Night in Florence Spaghetti https://food52.com/recipes/14030-first-night-in-florence-spaghetti but @inpatskitchen kindly beat me to it

i just made today a baked lasagna with tuna, besciamella, stir fryed onion and lots of grated parmesan cheese. no tomato sauce, simply delicious.

There is a deli near my house that serves an italian tuna salad with black olives, cucumber & preserved lemon - with crispy focaccia. Yum!

Giardinara, an Italian pickle, that can be mild or hot. Sometimes made with tuna, or tuna later mixed in. use it to top sandwiches, as a cold pasta sauce, as an anripasto. Many recipes available from chefs, restaurants, home cooks.
