I bought a dehydrator and dehydrate my own food:
Sweet potatoes and yams, celery root, rutabage etc. Mashed and spread on parchment paper covered dehydrator trays.
Beets, cut in chunks. Golden beets won't turn your whole meal (and your poo) red.
Slow-cooked chicken or pork tenderloin, shredded with a fork and spread on parchment.
Carrots, leafy greens, zucchini, corn, any other vegetable that is good eaten raw and not cruciferous, cut in chunks.
Olives (green or black, pitted).
Tomatoes and onions are easier to purchase already dried.
Mix up any proportion of the above items (i.e. a little of the meat, a little of the starchy root stuff, a little of the vegetables) in bags, enough to fit into a 16oz plastic jar with a secure lid. At breakfast, put lunch in the jar and fill with water. Eat cold at lunch slathered liberally in olive oil. After lunch, put dinner in the jar and fill with water. Eat cold just like lunch or heat it up and melt in some coconut butter, more olive oils or other fat. Start soaking breakfast at bedtime and eat just like lunch. Or else find something else for breakfast you like better.
Then there are the old favorites to eat for snacks: nuts, dried fruit, jerky.
