Tuna sandwich or Tuna Salad
this from the mens fitness magazine but a great "protein lunch " ! 
Don’t eat just another tired tuna salad sandwich. This time, add a can of chickpeas for a savory upgrade—and some extra protein. Simply mash the tuna and chickpeas, then add lemon juice, olive oil, salt and pepper. And if you’ve got onions and red pepper? Great. Chop them up and add them in, too. Serve your Tuna Salad 2.0 over leafy greens, or put it between whole-grain bread for a satisfying sandwich. (And if you’ve got to have the traditional kind? Go for it. But slash the fat by using Greek yogurt instead of mayo.)
