You simply need to make a conscious effort to use your canned goods. We use canned goods on a weekly basis.
here are a few comments I would like to share:
1. canned goods are much healthier and tastier than years ago. Prepared spaghetti used to be thin and tasteless.. Now some of it is home made quality! ( Ragu w/ Mama's meat sauce, Cattle Drive chile come to mind too) There are also low fat/carb type canned goods.
2. experiment and find what you like best and use them on a weekly basis. There is so much variety now that certainly you can find something that will suit you.
3. cheaper is not always better, but you can find some off brands that are as good or better than "name" brands only cheaper.Wynwood premium corn is an example of off brand quality.
4. canned goods can be convenient. Open a can of soup, put it in a tupperware container and micro wave it for lunch at work!
Maybe you can make vegetable soup from your canned veggies or a tuna casserole? Good luck!
