Same yogurt, but I’ll trade sardines for cooked salmon.
We have a very similar plan.
Before my paleo eating ways, I used to have the sardines with hard crackers and that might be the way for novices to start out. After a while, you learn to appreciate the sardines all by themselves.
I get (fresh) salmon often but it can also be good out of a can. Rubenstein's has a decent price for canned red wild salmon from Alaska.
