I've got a bunch more i used to be a roofer and water proofer burn more calories than you can imagine so had to eat all day long while working with dirty hands. Its really hard getting your diet in working 80hrs a wk I know but possible good luck and good gains brother

Canned tuna and chicken. Hard boiled eggs. Peanut butter, RTD protein/carb drinks.

Hard boiled eggs, canned meat tuna/chix breast, smoked meats of all kinds including fish, Peanut butter, blanched chilled vegetables, mixed nuts (no homo), grilled chix works tremendous as can be utilized with fresh greens (salad) sandwich, fajita, wrap etc. Pulled chilled rotisserie chicken also works great. You can also incorporate fresh fruit like blueberries, raspberries, mango, papaya, etc.

I always like to travel with a large thermos with a real food style shake I make in the am combining products like whey isolate, steel ground oats, and pasteurized eggs/whites. I combine with fruits and sometimes yogurt. Its a great way to keep the body satiated.

Another things I do, ever since I was a kid I have been hooked on cold cuts, which everyone knows totally blows for your diet. What I like to do is early in the week to buy large primal cuts - like Hotel style turkey Breasts and eye round roasts. I like to season, prepare, cook, chill, and then slice as needed in order to make my own cold cuts. In the offseason I also use meats like pork lions and lamb legs as well.

I hope this gives you some ideas brother.

For me it's all nasty cold. I'm always trying to find easy foods to eat cold. Like a lot of these guys said, tuna is always good. Peanut butter and some jelly on Ezekiel bread. If you have a good lunch cooler mix up grapenuts cereal and milk in a blender. It mixes well. I do two cups of grape nuts and 1.5 cups of milk put it in a shaker cup. That's 1065 calories right there. Fast and easy and it will keep you fueled through work. Hope that helps!

hardly ever have access to a microwave.

LMAO at your youngsters............ ok, I pre-date microwave ovens.

Have you considered tin foil and an exhaust manifold???. It just take a little planning.

I'm not picky. I rarely heat up leftovers at home.

Bagel salamon salad cucumber ketchup
.... here is a good begin read that this is intresting stuff + there are alot of ingredients in it that you can eat cold and you can combine the ingredients to a meal that you like https://www.eroids.com/forum/training-nutrition-diet/workout-exercise/th...

• tuna with rice
• ezekiel bread(4:9) with tuna and eggs (in form of a sandwich)
• self made tortillas rolled with chicken/tuna and salad inside.

Kind bars, tuna, trail mix, boosts/ensures, peanut butter jelly (roughneck samwhich), wheat germ if you got milk in your cooler, yogurts... im not good at prepping meals for myself when im out of town so just try and pack what i can on ice.
Rice and chicken is good cold i like them mre's lot of food in em just anything is better than nothing i like snacks i can fill my pockets with to eat while im working.

Yep bagged or canned chicken/ tuna is where it's at

Can of tuna with some balsamic vinegar on it with a handful of rice cakes, doesn't even need to be cold.
There are some chilled tomato soups, like gespatcho that you could toss some diced chicken and some rice in.
Steak salad travels well with hearty greens like kale.
Mediterranean style pasta salads with diced chicken would be good, a little red wine vinegar and olive oil to dress it.
Egg salad with bread on the side so it doesn't get soggy.
And what I call "the freshman" a pint of liquid egg whites straight from the carton and rice cakes. Got me through college.
