My DS's love my tuna casserole (see Recipe #349613), but one of them does not have a microwave at school to heat it up. I came up with this cold version of it and they both really like it. I kept it simple because after a long day at work and then making a nice dinner, I don't feel like making high maintenance lunches. My guys are 12 and 14 and can eat a lot, particularly this! You can increase the amount to make a cold salad for a gathering. Enjoy!
