Fruit skewers (think watermelon, grapes and rock melon placed on a skewer...they look fancy and everyone loves them...and it's cheap!)
Homemade hommus or avocado dip dips and Turkish bread (should be cheap if you make your own and get a big Turkish bread and cut into pieces)
Zucchini slice cut into bite sized pieces (should be cheap....just a carrot a zucchini an onion, some corn and six eggs and a bit of flour, I leave out bacon so it's vegetarian)
Little pastry cases or mini toasts (from the supermarket) and top with an avocado and tomato salsa. So tasty!
