Snack/Lunch for physical jobs

So, I've got a pretty physically demanding job, pic related, what's some good stuff to lunch/snack that can help my muscles keep going? What should I eat to maximize my work-related gains? All those energizing sport drinks are complete sugar shit, aren't they?

Protein shakes and shit that old people drink to stay alive

Like those vegetable smoothies that look terrible?

I struggle with this also. Very rough manufacturing job. I typically eat stuff like whole wheat peanut butter crackers, packs of peanuts, those P3 packs of nuts and cheese and meat chunks, pepperoni sticks, Rev turkey/ham wraps, string cheese (no time to peel it, just chomp that shit), celary sticks with peanut butter, or whole wheat tuna or peanut butter and honey sandwiches.

Naw....those chocolate,strawberry,and vanilla ones that taste like chalk. If you're speaking in a dietary supplement manner since you don't want to load up on meals and just want an inbetweener snack

Are protein bars any good for this kind of shit?

chicken alfredo
Homemade burgers
Salmon patties

Homemade granola. Easy as fuck, lasts pretty long for no extra preservatives, and you control your macros and flavors.

ensure you kill yourself promptly

shit made from oats like oatbiscuits or granola bars, bananas, various treated meats like jerky and shakes
