Eating healthy for the lazy with limited access to a kitchen

Since starting semaglutide, I've been trying to eat healthier, but it's been a challenge.

I live in a group house, which serves me well for most aspects of my life, but the most difficult aspect is consistent access to the kitchen. The refrigerator is always full, the prep area is always messy, and I don’t really spend much time at home anyways. I travel a lot and generally work out of coffeeshops, which all serves me great. 

The kitchen is so difficult that any time I buy healthy food it just ends up rotting in the fridge or disappearing. So then I end up eating out for most of my meals.

I eat generally healthy, and since starting semaglutide I definitely eat out about half as much per day, but I'd still like to find ways to eat healthier.

Does anybody else out there in a similar situation have things that have worked for them?

I have had some luck with pre flavored packages of beans and rice that I microwave in the morning and pack for lunch. Overnight oats can work too. I keep the ingredients in my room so access isn’t as much of a problem that way.

Coffeeshops have decent food but it’s a lot of carbs (and not cheap). Avocado toast is usually the healthiest option on the menu. 

Some other things have in the mix… 

- canned fish on rice cakes with avocado

- pre-washed snackable veggies (carrot sticks, little peppers)

- “protein” / “meal replacement” bars

What would you do in my situation to eat healthier and not go broke? 

Any thoughts or tips are appreciated?
