Butter

We found an awesome product, Olivio Coconut Spread, to use as a butter replacement. I've gotten used to it and have actually grown quite fond of the taste. It has a buttery mouthfeel and is kind of sweet. It melts like the real stuff and is fantastic on toast, especially with a bit of cinnamon sprinkled on top.

Even my husband likes it, and he doesn't like the taste of coconut.

"Soy" sauce

This is spendy, so it's one of the items that I tend to only use in recipes that the whole family will eat- or he uses it on rice himself. For the rest of the family, we still use Bragg's Liquid Aminos. We find this at Whole Foods. Careful with it- the first one we bought exploded on the WF cashier when he bumped it on the counter (glad it happened in the store where they replaced it, rather than at home).

I like to wait to find it for $5.99 on sale and buy a few at a time so I have it on hand.
