I'm creating a cookbook, but don't know how to organize the categories, can you help?

it's mostly for healthier dinners and for kids/teenagers to use in the house. there won't be drinks or appetizers, and i can't think of any ways to organize the recipes besides "ceroles/pasta" and "soup/salad". i'm using a binder with dividers to make it easier and not having to flip through 200 recipes. any ideas? the food is mostly dinner meals like ceroles, crock pot, stir fry, and sandwich things.
