I do a similar idea. Basically, this time of year we have a lot of extra produce. So Swiss chard, green beans, shredded zucc, tomatoes, etc. go in the freezer. Besides that, I make a lot of BIG pots of soup with garden veggies. I call it "backyard stew." We eat 1 meal for dinner the day it's cooked & then freeze the remaining 2-3 dinner portions. I do it 1-2 times per week, so we can pull it out when needed. (I teach sci for a home school co-op, one day a week. It's a long day, K-10th, a 40 min commute in Chicago traffic....+35 min back home. I'm pretty worthless by the time I'm home. The day before is spent planning & gathering supplies.) On those days, I often want a simple heat & serve meal.
Our house is used to much of the meal coming from the backyard, but the rest of the family gets a big kick out of it. Therefore, a jar of pickles, loaf of zucc bread, cherry pie filling, or frozen bag of backyard stew make great gifts.
My sister did the once a month cooking. For her big family of 9 & home schooling it was a necessity. For me, it's just a way to enjoy garden produce year round and reduce the grocery bill.
