Don’t forget seeds! If you don’t garden regularly, start now. You don’t want your first garden to be the one your life depends on, there’s too big a learning curve for that!
I don’t do too well on low protein diets. Tomatoes and potatoes are about the only thing I mess with anymore. Some garlic. I do like spinach and I stocked up on that at Walmart. 6lb cans for 4.72, shipped.
Good luck!
