Recommend any general foods/brands that are healthy?

I really struggle as an "emerging adult" to take care of myself. I experience depression and chronic pain, yada yada. Meal prepping, hell, even cooking, is beyond my current capability. When I say cooking, I mean anything that takes more than 5 minutes.

I typically order out, and I need to cut down on it. Grocery shopping is daunting. Sorting through the food label information and trying to understand the research behind what is a "healthy" food is daunting.

Can anyone just recommend brands or foods that I can easily go for, preferably won't break the bank, and are generally "healthy"? Many thanks!
