Is there an easy way to test how many calories are in a certain

Look up the individual ingredients beforehand.

well yeah but like I said our deli does not have caloric information. I usually make myself a turkey sandwich on sourdough bread (probably gonna start replacing with wheat) that has 4 or 5 slices of turkey, a slice of muenster cheese, a touch of mayo (which I am going to start not putting on at all and maybe sub for a healthier dressing), jalapenos, green olives, lettuce (which I will probably start replacing with spinach), onions, and sometimes a coupel tomato slices. Obviously being that it's deli food there are going to be plenty of preservatives and shit but when I get free food here I don't worry too much about that.

I guess I could probably find calorie counts for the veggies and shit, but for the bread and meat they don't have anything to show it, we get our bread pre-baked from an in town bakery. I guess I could call them and ask, didn't think about that til now.

Chem student here. Any bomb calorimetry you could do is shit-tier and will certainly be less precise than just weighing the individual parts and looking up their calories by mass.

Take a little scale and weigh it. Look up how many calories are in that type of food online after you have the weights. Only have to do it once really.

It's not really an answer to your question, but if you have lettuce that isn't shredded you could always replace the bread with lettuce and use that to hold your sandwich together.

i could do this but it seems like i might as well just make a salad at that point, which would probably be healthier anyway

Throw it into a calorie declassifier scanner.
Kinda like that thing from spongebob where Patrick was trying to find out the secret recipe to the krabby pattt

Chain restaurants with more than 20 locations are required to have nutritional information available. So, if you go somewhere like that you can ask, if not then sue.

That's probably true. It's purely for the convenience of eating in a sandwich-esque format.

Your actual question has already been answered so I didn't really have anything else to add, but I wanted to share a little thing I do that helps during cuts.
