I don’t have any precise recipe ideas but I have cerbral palsy and have some trouble lifting and balancing with heavy things. One thing I’ve found pretty helpful is having a cart that is exactly counter height. That way I can cook with a heavy pot on the stove, then slide it on the cart as easily take it to the sink to strain or whatever, and also take things to the table without much lifting.
What about going breakfasty? Make omelettes, scrambled eggs, pancakes, french toast, egg sandwiches? Cheap and pretty easy to make. Even do good old classic eggs, bacon, and toast.
Buy some pizza sauce and whatever topping you like, and use either an English muffin or half of a bagel to make miniature pizzas that you can pop in the toaster oven to bake for a few minutes. If you really wanted to go flavorful, get a box of texas toast to use as the crust.
If you use the Crock-Pot, you can make a roast, and reuse the leftovers for BBQ sandwiches (or pulled pork if it’s a pork roast), beef and noodle soup, taco filler, etc. Basically make more meals out of it.
A very simple meal is buy some tortillas and shredded cheese. Can either microwave or heat in a skillet as a cheese quesadilla. Feel adventurous? Add some cooked chicken, leftover roast, onion, peppers, whatever! Could also make sandwich wraps or pinwheels out of the tortillas.
After I had my stroke I ate nothing but progresso soup for like 3 months. They have every flavor soup you can imagine the calories are pretty reasonable and I would eat the whole can as a meal even though half my face is partially paralyzed around the mouth I just didn’t eat a lot in public. to dress it up you can add like a few slices of cheese to nibble on or crackers or a couple of vegetables or for some of their like Mexican flavor soups you can add a tortilla. If you get bored of their flavors I would switch over to the Campbell’s condensed flavors. They’re lower in calories because it’s a smaller can and they’re condensed and all you really add water but they are also a little bit more affordable so not all bad. Good luck!
If you have trouble with knife work, there are adaptive kitchen tools, such as rocker knives or one-handed cutting boards that help with grip or arm strength.
Maybe bean salad is an option? You can use canned beans so you don’t have to lift a heavy pot.
How about baked potatoes, or sweet potatoes? Things like canned chili as a topping to make it a complete meal.
Sardines or tuna on crackers or toast. Avocado toast. Nibble-style meals, with things like fruit, cheese, and pre-sliced meats. Yogurt. Oatmeal.
An electric steamer with plastic trays is light and easy to clean up. They can do rice, vegetables, and meat. Steaming thinly sliced chicken strips or fish fillets is also healthy. I used to eat a lot of steamed broccoli, chicken and rice with a bit of salad dressing.
I also recommend a sandwich press, or a panini press. You can cook thin cuts of meat on these and you don’t have to lift or move them to clean, just wash with a soapy sponge and then wipe it down. You can also make delicious toasty wraps, sandwiches, quesadillas, pancakes.. My most-cooked meal on these is a simple egg and toast, with optional fried tomato with basil.
