Unfortunately, you're both at the point where you need great meals to help you get through your hectic days. It's going to have to become a priority, and sacrifices will have to be made to get to your goals of healthy foods in a timely fashion.
Some of the advice that I have for you is as follows. (By the way welcome from Lurkedom!)
1. Take a look at your schedule, is there a block of time that you can both work together to get to your goal of healthy eating? I would spend a couple of hours on the weekend to work with DD to spend some time together and prepare some meals ahead of time. The night before you plan to work, I would put a pound of dried beans on to soak overnight. During your work session, plan on doing something first with the beans.
You can use those in pasta salads, lettuce salads, chili, bean and vegetable soup, in rice, etc.
Having reactions to food(s) is difficult but not impossible. I'm going to stick with a meat, starch, vegetable fruit because I'm not sure what you can eat. This is just for inspiration.
During the work session, you can roast a large chicken. You can keep it healthy by stuffing it with citrus and herbs. It doesn't take long to make a nice chicken dinner. If you like you can have a meal of chicken, roasted potatoes, lettuce salad and a fruit salad. After dinner on the first night, you can carve the meat off of the bones, and put the bones on to make a nice stock. Garlic, onion, carrots and celery will help make a nice rich broth. The rest of the chicken you could package into baggies to top salads, or to make some sandwiches.
While working on your weekly meal plan, I would make either a quick bread or muffins, for great sides that require little work after they're prepared. For the menu below I used corn bread and muffins.
If you want a little dessert you could bake up a cake, cup cakes, crisp, cobbler.
To help streamline lunches, I would make a huge lettuce salad and a fruit salad. The fruit salad can be eaten as dessert, breakfast, lunch, dinner sides, or as a snack.
You could also whip up a pasta or vegetable salad too, to help with lunch preparation.
For that same work session, I would put in another type of meat. For instance a pork loin would be nice.
Here's a sample way to use your food bank of investments. I would try and prepare food on Sunday to help us get through the week. Saturday night then I would put the beans on.
For this menu you are preparing three proteins (Roasted Chicken, pork loin, and a pot of chili) two salads (lettuce and fruit) two breads (corn bread and muffins). The rest is just individual pieces of fruit, vegetables, and either noodles, sweet potatoes, or rice.
Sunday: Dinner: Roast chicken, roasted vegetables, lettuce salad and fresh fruit salad for dessert.
Monday: B: muffins, yogurt, fresh fruit salad.
L: Lettuce salad topped with chicken, whole wheat roll and a piece of fresh fruit.
D: Chili, corn bread, and fresh fruit.
Tuesday: B: cereal, milk (or soy or almond)
L: Yogurt, peanut butter sandwich, piece of fruit
D: sliced pork, baked (microwaved) sweet potatoes, steamed broccoli
Wednesday: B: scrambled eggs, toast, fruit.
L: Chili with cornbread, piece of fruit.
D: In the morning in a slow cooker, put in stock, chicken, vegetables and allow to cook all day. Add noodles when you come home. Chicken Noodle Soup with muffins.
Thursday: B: cereal with milk
L: Chicken sandwich with lettuce and tomato, packaged separately from the bread. Piece of fruit.
D; Pork Fried rice, chicken consomme and piece of fruit.
Friday: B: Toast with fruit.
L: Pork fried rice, fruit (This can be eaten cold too.)
D: Chicken Noodle Soup, lettuce salad.
Saturday: Omelettes with toast and fruit.
D: Something fun to reward yourselves for a great week.
Here are some ideas that work for me, maybe you'll have some success with them, too. When clearing up the dinner dishes, prepare the lunches at the same time. You'll only have one clean up time. Since mornings tend to be hectic this could save you some time too. I also use this time to put the food in the crock pot. That way I just need to remove from the fridge and put into the crock pot as I'm headed out the door. A great morning time saver.
When preparing food for ahead make sure that you're refrigerating when you're finished with that food.
