If you're wanting some ideas on how to create some fun themed meals, here are a few letter and color suggestions with recipe links.
Foods That Begin with the Letter A:
-Arugula leaves with chopped and toasted Almonds and diced Apples with Annie's Natural Dressing (your choice of flavor)
-Artichoke Alfredo over Angelhair pasta. Here's a link to my Fettuccine Alfredo. Instead of using the fettuccine noodles, use angelhair noodles, and add 1 can of artichokes (13-15 oz., the kind that come packed in water). Drain most of the water from the can, then cook them on the stovetop over medium heat in a tiny bit of water for about 5 minutes. Add them to the alfredo when you're adding the noodles. It's delicious.
-Arnold Palmers or Apple Juice for drinks
Foods That Begin with the Letter B:
-Brown Bread with Butter
-Breakfast Bao. All the same ingredients, except when you come to the pork, use Jimmy Dean pork sausage and scramble a few eggs. These are so good!
-Broccoli Beef. I have 2 different Broccoli Beef recipes, so look them over and see which one you like best! Broccoli Beef 1 or Broccoli Beef 2
-Belgian Beer for drinks
Orange Foods (I've done this theme for Halloween a few times):
-Cheetos (for one meal a year, it's totally acceptable)
If you don't want to make the orange chicken, you can always make macaroni and cheese!
-Orange Juice to drink
Have fun being creative!
