MUCH depends on purpose and length of storage. If you're talking just yr to yr or two "normal"...or a SHTF prep.
First, make a list of what you will eat. Next look at nutritional value of those. Look for proteins, carbs, vit/ min...balance. I look for 2yr use for most veg types & a year on meats -- for what I'll eat. Guess we're not considering the freezers
Next I try to grow most popular eating for me. But will buy if value there with expense of time/material to can is there. This being my normal, yearly method. Plus I can some convenience things.
1. Tomatoes in all forms. Whole, peeled and cored, sauce, spaghetti sauce, salsa, etc.
2. Vegetable Soup from whatever is in the garden.
3. Chicken-home raised
4. Broth
5. Jams and jellies
6. Fruit
7. Green beans
8. Pickles-you have my recipe!
9. Peas although I like them better when frozen.
10. Pinto beans because I want beans now and didn’t think ahead enough to soak them overnight and simmer all day.
