Sea Salt (for me)
Pepper (for both of us)
Mrs Dash for both of us
Crushed red pepper or Texas Petes or Louisiana (both of us)
Italian Seasonning blend (both)
OK, that's five, but one is only for me... does that count as four???
Yes, I carry more than that on an extended trip... garlic powder, basil, tumeric, mustard seed, cardomom, curry and others, but,
we've easily made it three weeks with basic four.... Ii prefer to buy good produce and meats, and let the flavor come thru.
