My diet isn’t too SAD most of the time. 3 meals a week are Blue Apron, which is kind of pricey, but it’s a much healthier option and has taught me how to actually cook. It’s a lot of chicken, salmon, rice, and vegetables. The meals are usually too big, so I take leftovers as 3 lunches a week.
The rest of my meals are sandwiches or salads from local places that are healthier, with a splash of frozen vegetables with rice and usually chicken.
I fill up on seltzer, tea, and water, so I tend not to snack too much. And I try to keep better snacks like fruit and nuts more often than chips or cookies.
