I hear you Trish! I've been so hungry the last few days.
Sorry if I repeat some that have already been said:

Carrot/celery sticks with dip
Raisin toast
Muffins - sweet or savoury, heaps of recipes on BB!
Pikelets - easy to make and the kids will love them too!
2 min noodles (cheap and easy!)
Ice cream or frozen yoghurt for a healthier option
English muffins with your fav topping ( i love them grilled with cheese & tomato)
