I eat dandelion roots, raw and cooked, from my pristine country yard (so blessed!). I just pick (okay, dig) and rinse, put in water (grate in ginger and cinnamon, Italian seasoning or whatever you like) until just about to boil, pour off into cup, drink the tea water and eat the dandelion. Carrots are great, too, I just don't waste money on them since I have fresh, wild dandelion which is so superior to grocery-store carrots. Started our garden this year, though.
I drink Aroy-D coconut milk because it is very cheap at asian markets and the only ingredient is coconut milk, the boxes are BPA-free.
Clean, canned mackerel, oysters, herring and sardines (no junk oils, of course) are a lifesaver. So affordable and you get bones and skin and other organs in most types!
Plenty of avocados and tallow, liver once a week, and make bone broth very often. And heaps of eggs, duck and chicken - I like duck eggs best but $$$.
If and when I do eat dairy, it's raw or grass-fed or both, in a hard, sharp cheese, and not every day. Occasional sips of raw milk seem to go well, but not a whole container at once.
