i get really hungry too when i'm riding regularly. i also have little time to cook, so between larger meals i fill up on these, because they are quick and easy:

pasta with ragu sauce
peanut butter and jelly sandwiches
tons of bananas
tuna fish sandwiches (can of tuna with a little mayo and maybe a slice of cheese)
granola bars
baked potatoes

if i do cook a proper meal, i try to do something that will create leftovers for a few days. personally, i love left overs after a ride or late at night. you get the food quicker and with less hassle.
