I want to mail some healthy dinners to a young widow. I would like the foods to be ready-to-heat or simple in that they just require adding one or two ingredients like water or milk. Even adding a cooked chicken breast would be okay if everything else was in a mix and required no work. She is having a hard time getting herself to cook, let alone cook something healthy. She was trying to stick to a "heart healthy" diet due to a family history of cardiac disease before her husband passed away.
What are some options for room-temperature-stable dinners that can withstand 2-day shipping in hot weather? Some things I thought of: dry pasta, Hamburger Helper, and ramen noodle bowls, but these are not healthy. There's Tasty Bite Indian dinners which are entirely sealed and just require boiling, but I really would like to do the preparation myself. She can go grocery shopping herself, so I don't want to mail basic things like canned vegetables or soups.
Please note that I would like to prepare the dinners/ dinner mixes myself and I cannot afford a meal delivery service. Thanks!
