Wedding Food: Lunch, Dinner, Dunch or Linner?

Our wedding is taking place in January, at 3pm. Now I know this isn't really lunch, nor dinner. It's actually 'tea-time' (being originally from England). I'm having a real hard time deciding on foods to serve. I have a list of a couple appetizers and of course soup but should I actually serve entrees or just filling appetizers? Plus, I dont want people to leave starving commenting on how there was no food. I'm planning on making it myself and no recipe is too hard. Help me out if you can! Thanks
