The thing I really like about it is its versatility. If I need to feed a crowd, I make it in a 9 x 13 pan. Having vegetarians over? Just use vegetables. Non-vegetarians? Add layers of thinly-sliced ham. Vegans? Oh, you got me there. Make them something else, not a strata.
A variety of vegetables work in it, such as tomatoes, roasted red or green peppers, spinach, artichokes, etc. The texture is somewhat souffle'-like, which makes it a tad swanky. Like me! Well, that's what people say.
This makes a side dish for two, with two slices over to reheat the next day. (It reheats beautifully in the microwave.) Here's how.
Notes: Whole-wheat bread doesn't work well. Also, this can be put together the night before, popped into the refrigerator, and baked the next day. It becomes even more souffle'-like that way. If you really dress it up, that makes it a great meal for Christmas morning.
