Prepare the Annie's Four Cheese Macaroni & Cheese according to the instructions on the box. This usually involves boiling the pasta, draining it, and mixing in the cheese packet with a bit of butter and milk as directed.
While the macaroni and cheese is cooking, place the chopped BBQ pork rib meat in a microwave-safe bowl and reheat it in the microwave until warmed through. This typically takes about 1-2 minutes depending on your microwave's power.
Once the macaroni and cheese is ready, add the warmed BBQ pork rib meat (from Step 2) to the pot or bowl of mac & cheese. Stir well so the meat is distributed evenly throughout the cheesy pasta.
If you like your mac and cheese extra cheesy, sprinkle shredded cheddar cheese and grated Parmesan cheese over the mixture. Stir until the cheese melts and blends in. I always add a bit of extra Parmesan here for some extra oomph!
Spoon the mac & cheese mixture into serving bowls. Top each serving with a dollop of Annie's Organic Upside Down Ketchup, if desired. Serve immediately while hot and creamy.
