Tuna fish

Some canned tuna ideas:  white beans, pesto, roasted peppers; broccoli, sun-dried tomatoes, vinaigrette; green beans, diced new potatoes, boiled egg, vinaigrette; spinach, lemon juice, EVOO; LF ricotta cheese, garlic, EVOO, whole-grain pasta

You just can't beat a can of tuna for convenience.

Im sure it depends on the individual, but eating tuna every day might put you at risk for high mercury levels. I too eat a lot of tuna, but have been trying to limit to 3-4 times a week because of this fact. I like olives, greek dressing, red onion, and feta thrown in a pita - Mediterranean style. Oh and BBQ  & bacon bits topped with cheddar.   Mmm mmm

I was under the impression that "light" tuna was lower in mercury than "albacore" tuna.... So I have canned salmon as well. 

In my tuna/salmo I like mayo, seafood sauce and chopped up hot peppers.  Sometimes I substitute creamed horseradish in place of seafood sauce and mayo.
 

I usually go with the 3 oz canned salmon for lunch.  Tasty add in:  1/3 can black beans, 1/3 can chopped tomatoes, couple of table spoons of salsa.  combine the four, makes a nice lunch in a bowl.

I also like substituting italian salad dressing made with balsamic vinegar and olive oil for the mayo sometimes.  Eat it on Triscuts. (whole wheat not much else)

x2.

a few others...green peppers, diced apple, raisins. 

I mainly try to make it w/ tons of veggies, 1/2 can of tuna, and a tiny bit of mayo. 

when you drain the pineapple juice out of the can, save it and use it in the tuna.  sounds insane but it's awesome.

i also like just doing brown mustard, but that is VERY dry.

Yes!!! Grapes, celery, a little bit of onion and some mayo. Sounds weird, but it's totally not! Walnuts would be good...

No matter how I try to explain it to the people I work with:

Tuna, Mayo,Pickle relish can easily become

tuna, cottage cheese, Pineapple---low fat wheat thins in the side

Tuna and sweet corn!

have been having tuna, sweet corn, spring onions and cheese melts since I was in highschool! yum
