I was making eggplant parmesian and cooking butternut squash today so I put a big chuck of squash, cooked, right in the center of the eggplant just for fun. I was in the fridge and I decided to try making one quarter of the dish with some blue cheese on top. I encourage all my student to use their artistic creativity in the kitchen. Remember there are no rules in the kitchen. If it tastes good, cook it.
