Meals without cooking/blending? Help!

Hey guys! So I have a question and was wondering if anyone can give me some suggestions or advice.

My husband and I are recovering addicts (over 8 months clean) and are living in a couples shelter as a result of our addiction. This severely affects the way we eat and makes it so much harder to be healthy. The shelter serves 3 meals a day but more often than not, they are disgusting. Now, we do have our own room and own mini fridge so we do have our own foods such as oatmeal, cereal, granola bars, fruits, sometimes veggies and honestly, that's pretty much it. A lot of times we buy just what we're gonna have for the day because we are short on space with just a mini fridge.

We aren't allowed to cook which absolutely kills! So that by itself eliminates so many good, healthy meals. We also cannot have blenders (bye, bye homemade smoothies), hot pots, coffee machines (so depressing but I do buy coffee every morning outside but can't bring it in because we aren't allowed to bring in unopened bottles or fountain drinks! Insanity! They're so afraid that people will drink alcohol but they do it anyways, duh!) and we also cannot bring in cans, tins or glass bottles and like I said just a second ago, we also cannot bring in unopened bottles, fountain drinks, coffee, shakes or smoothies. So as you can imagine, it's tough to eat right, lose weight and enjoy your meals without spending a shitton of money that we don't have or else we wouldn't be living in a shelter.

So the question is: do you know of any good meals or foods that we can eat without cooking or blending? We can microwave but it is a bit of a hassle but I would definitely be willing of course.

We do have oatmeal, fruits, fruit salads, veggies, granola, but aside from a that, I'm honestly as a loss. I just don't know what else to make or have that isn't 1,000 calories per bite haha.

Thanks in advance!
