i don't think making lean cousine type of meals would work that well. it can work sometimes, if you add extra veggies in. the meal on it's own isn't filling enough in my opinion.
instead see what you could make with the time you have. i'm home all the time, but i've found staying out of the kitchen key, as much as i can. then i'm not snacking while i'm in there.
make a few dishes on the weekend, or 1 weekend a month. freeze/fridge portioned out and ready.
make things that literally take 5-10 min.
quick burrito with canned beans. whatever toppings you like.
lower fat version of tuna/chicken salad. i use basil and light miracle whip, instead of mayo.
eggs. omelets can be great even for dinner. lots of veggies thrown in. some people make a quiche, then eat from that all week. really easy egg dish. you bake in the oven, then just slice off pieces for breakfast all week.
couscous(coos coos) it's a kind of noodle that takes almost no time to cook.
rachel ray has a million tips of how to make good food fast. i often use her ideas as inspiration for flavors or dishes, but many of her dishes can be made in less than 30 mins.
