Hi Francis, in my part of the midwest with sandyish soils, the no brainer stuff is:
beans, kale, snap peas, cabbage, potatoes, garlic, onions (from starts, not sets or seed), butternut squash, zucchini, red orach and non-bell peppers
raspberries, strawberries, honeyberries, asparagus, apples, oregano and sorrel
"Hundreds of years from now it will not matter what my bank account was, the sort of house I lived in or the type of car I drove... But the world may be different because I did something so bafflingly crazy that it becomes a tourist destination"
For me, corn, okra, & tomatoes have been easy annuals. Basil, mints, parsley, and rosemary for herbs; and asparagus as a perennial. In my climate, greens like kale & chard are biennial; and give me fresh greens all year; while spinach & collards are easy, cold-season crops. Malabar spinach is an annual green that will produce all summer long and reseed by itself. This year I've started artichokes from seed, and they've been easy so far, but they're only a couple of months old.
I've historically had trouble getting beans & peas to produce. This year I'm trying a lot of different types of beans to hopefully find something that will do well for me.
But I agree with Anne's comment. Start with the stuff you like to eat. Also, it's all a learning experience, so don't get discouraged if you don't have immediate success with a certain crop. If something doesn't do well, it's always worth it to make notes & try it again using different variables. A lot of times, it's just a matter of finding the right conditions in your environment.
Potatoes are the easiest things for me. Put them on soil and cover them with something, soil, wood chips, straw, anything. If you lay a potato on your kitchen floor, it will grow sprouts right? Give it any chance at all and it will grow.
