Main question is do I have modern knowledge or not?

If yes - then apply everything I know from primitive technology and education. Will try to reach some level of progress, probably will be able to get to steam machines and telegraph in one lifetime.

If no - then will be just strolling with everyone and enjoying nature as usual.

Oh, then it might be a bit harder, but you just need something greasy to compensate the dry. Onions give some of it already, and maybe even without bacon they will just do the job. Just take two onions instead of one, and fry them for longer.

And this is the foundation, spices are up to you, I go moderately crazy with paprika, koriander, basil, pepper and whatever is required to finalize the taste. It forgives a lot :) Buckwheat I use is the dried brown one. Probably with wholegrain one you even don’t need to compensate that dry that much as well.

Good luck!

Buckwheat is so good if you fry onions, carrots and bacon, and then mix with boiled buckwheat.

Also if you don’t use multi-cooker - consider. It is a bit hard to get used to, but gives additional freedom in cooking everything from your list with meat.
