Cooking for my pregnant wife

The times Frances and I eat dinner and other meals can vary from day to day. I like to cook and I've gotten to do it more since we've been blessed with the pregnancy. Frances' eating habits have varied even more since then. Back in the first trimester, we never knew when Frances was going to be hungry, so we had to capitalize on every opportunity. Bearing that in mind, read the following exchange:

"Can you make me something?" Frances asked.
"What would you like, dear?"
"I don't know. But when you make it, I'll know."
