We split it pretty much 50/50. I'm the one to cook the tried and true foods and Toby is the one to experiment. He likes to make up recipes and try new things.
We eat pretty much anything from bland to super spicy. Our whole family is VERY fond of pasta dishes and steak.
Now baking...ugh - I don't like to bake. Toby and Emily (my daughter) are the bakers!
