Choose some vegetables that are easy to grow, store well and that you like to eat. Some suggestions are varieties of dried bean, green bean, onion, broccoli, cauliflower, sugar snap peas, and carrots. You could also try your hand at plum tomatoes, although you will need to learn how to can them. Dried beans are about the easiest to store. In most cases, you can leave them dry right on the plant and then harvest them at the end of the season.
Onions are easy too.
Green beans, broccoli, cauliflower and sugar snap peas can be blanched and frozen in freezer bags. Carrots can stay in the ground until early winter. Remember this is your first year at this.
