I usually have about 300-350 for breakfast (depends how much milk I pour on my cereal!), about 300 for lunch, and about 600 for dinner, with snacks here and there and at least 2L of water. Sometimes I have more for dinner and less snacking. Sometimes I snack, have lots of dinner, and have more snacks!

On workout days I will always add a Dannon fruit at the bottom yogurt which is about 150 cals, which I eat right after my workout, and sometimes an extra glass of milk.
I like to have dinner be my big meal of the day and have lunch be the smallest, so I eat Lean Cuisines for lunch that are between 200 and 330 calories. (I only have LC and water for lunch, nothing else.) This way I have a lot of flexibility as far as what I eat for dinner goes -- if I really don't want to cook, I can have a sandwich from Boston Market and still be in my safe calorie range. I've kind of fallen off the fitday.com bandwagon, so I don't know how many cals I've been eating lately, but I haven't changed my eating habits much so I'm guessing I've been eating somewhere around 1300-1600 lately. Since we had junk food in the house, I've been having a piece of cake and a glass of milk each night which probably adds 300-400 cals or so.
