I have an outdoor job and many other things that keep me hopping---I don't have a lot of time for meal preparation, so any ideas on how to eat good tasting, healthy meals with little or no preparation or expense, would help me out tremendously. I also need to keep to an inexpensive budget.

Good tasting and healthy with little to no prep is a tall order. Large volume prep and portioning out is a different story.
You are especially limited if you don't have easy access to refrigeration and a microwave.
I decided long ago that food was no longer going to be a form of entertainment or enjoyment...just fuel my goals.
Now many here would suggest that this mindset could lead to a tendency to "fall off the wagon" and I would agree with that. But I happen to love dry tuna and cottage cheese and steamed brocolli, so every day is a treat, even though it's unintended. When I'm hunting, or on a jobsite, I always have tuna, plastic forks, and a can opener in the truck.

I think you can easily figure out some tasty foods that fit in with the nutritional plan I'm sure you've spelled out for yourself, but you may very well need to accept that you'll need to prepare in volume and eat the same thing for a while, until the next batch of whatever is made.

1) Fruits - Can't really go wrong with any of them. Dried fruits are pretty good too. I always have a bag of dried fruits at my work when I want to snack.
2) Peanut butter – Natural peanut butter (ingredients should just have peanuts and maybe salt). Can't really go wrong with a batch of peanut butter sandwich.
3) Tuna - Easy prep and east to eat on a salad, etc.
4) Chicken - Just broil over night and freeze, then microwave and pack in whatever you wish or eat it without anything.
5) Beef jerky - Good protein and great snack item.
6) Broiled eggs – you can pack this in your lunch
7) Veggies – things like cucumber, broccolis, carrots, etc can easily be packed with you and be eaten on the go.

Well I have more, but that's just what I have in mind from a quick thinking. But I'm sure you can figure it out based on that list.

Thanks Krodad and Dallen. Good ideas. I will need to work this out. I gotta stop eating the hamburgers. At least now I rarely eat fries. I like 'em too much to get rid of them completely though.

Yes, I forgot about beef jerky. I eat it often, turkey jerky as well. too much sodium of course, and other nasty things I'm sure, but it's a high protein, low carb source that travels great.

Sandwiches?

Use whole wheat bread, load them up with vegetables and turkey or chunk light tuna, use mustard and pepperocini to spice it up.

Or peanut butter (without hydrogenated oils or added sugar) or other nut / legume butters.

You mean boiled, not broiled?
