using a spider, I distribute the veg over the toasted bread and I add enough liquid to moisten the bread well but not make it soggy.
it’s best to stir it up, let it sit for a few minutes, check for moisture level and add more if it needs it.
You might need to adjust the seasoning at this point as well.
Once I have it where I want it I cover it with butter and throw it in a 375° oven until it’s nice and toasted on top. (final pic incoming.)
