Toast itself? Nearly never.
Its, for me.. one of those things that is too 'simple'? Like, I know it is good stuff. I've had it. I'll not turn down a good piece of toast with nearly whatever condiments are available. (Although I'll never order an avocado toast. Ever. I'm sure it is nice, but hell no.)
But yeah, it is too simple for me to think about. When I look in my freezer and see the bread, I'm thinking more about what I can add that to.
Like vegetables, I guess. Its a thing to add to another thing. But every so really rarely I'll see veggies and think.. ratatouille? Hell yeah. (Having a usual assortment of 'summer' type veg, anyway)
Sidenote: But if we were to talk 'toasted', then I prefer everything toasted. There is a nice burger joint around here that specializes in 'toasting' everything. The burger gets a tiny layer of burnt, the cheese gets a tiny bit of burnt.. the bread is just icing on a toasty cake. They have some sweet potato french fries that I havent.. quite.. gotten used to, yet. I think the sweetness is fine, but they really dont get the 'crispy' frying treatment like normal fries.
So yeah.
