Going veg and need a hand
Dreads and Diets
Like you said lentils, split peas, beans, rices, grains, all last long enough you can buy them in surplus. Quinoa is a personal favorite of mine being super high in protein. Potatoes last a relatively long time, go with sweet potatoes for more nutrients. Broccoli and Cauliflower tends to last a bit longer than the softer veggies, onions, garlic and such also preserve themselves. Leafy greens spoil quickly, but also don't take long to grow so that would be one that's ideal to grow at home. For fruits, although they are best ripened on the plant, you can buy them somewhat raw and let them ripen in your home. I have been looking into eating seasonally recently and it seems to have quite a few benefits, so you might want to consider looking into that yourself.
