Help with dietary and nutritional needs!! How can my family and I eat healthy in these cirstances?

Here's the situation: my wife is disabled. I dont know how to cook. My daughter and I don't have time to cook, either, with all of the chores, job/work/college, and caregiving. My wife used to cook, but with her disability, she can't. I've recently become concerned about my family/s nutritional needs. We havent had a home-cooked meal in about 10 years. We eat tv dinners, fast food, prepackaged and processed food regularly. We do eat out, but that food isn't exactly nutritious either. (applebee's fattening stuff) Could someone recommend a menu, a website, quick meals that are nutritious,a multi-v --anything!! Should I buy as many fruits and veggies as possible and eat those raw (and just get meat and chicken through take-out, etc) I need some help, please. thanks. And please don't make fun. It's incredibly difficult to worry about nutrition when you're a caregiver and managing a household, especially since meds cost so much and fresh food is so expensive.
