These are all very situational. Assuming that the tuna is canned and not fresh, that I'm not running a 50 or 100 mile ultra marathon ( which I have stopped doing), that I'm not enjoying the sandwich with a bowl of tomato soup, and that I made the chicken salad. Oh, and if more choices were available, Roast Beef would be #1, followed by ham, ( carved fresh), and banana with mayo.
1. Chicken Salad
2. PBJ
3. Tuna Salad*
4. Grilled Cheese
5. Fried Bologna
I may do another thread soon with another 5 sandwiches... some good roast beef is hard to beat.
