Offal - Offal (or organ meat, e.g. heart, kidney, liver, tripe, etc...) is usually mixed in with the veggie meal, because many dogs do not like the taste (some do). Just be careful not to feed too much, too quickly, as offal is very rich and too much will cause loose stools. Offal can be fed once or twice a week!
Veggie meal - This is for 1 meal not a full day's worth - 1/4 calves liver or an egg and I puree these veggies for about 3/4 cup worth. Mix and match veggies do not try to use all these at the same time - carrots, turnip, parsnip, green beans, yellow squash, zucchini, dark green lettuces, celery - I add a little - very little - of either spinach, kale, turnip greens, or broccoli. Now and then if I have a piece of cauliflower I toss that in too.
To most meals I add 1 teaspoon of oil (cold pressed flaxseed, or safflower or vegetable or olive but usually flaxseed for Omegas). To each meal I add 1 teaspoon nutritional yeast (Vitamin Bs), 1/4 teaspoon kelp, 1/4 teaspoon alfalfa powder. Also I add Vitamin C (about 2000mg) but you need to start off slow and increase a little at a time so as to not upset the tummy. My golden gets 200mg Vitamin E 1x/day
