I purchase a picnic pork roast from Macey's. Put the pork roast in the crock pot. Put the seasoning packet, ketchup, brown sugar, and apple cider vinegar in a separate bowl and mix together (specific measurements are on the packet). Pour over the roast and cook on low for 8 hours or high for 4 hours.
When its done cooking, shred the meat and remix with sauce. Serve on a fresh roll or bun. It's very easy and super yummy!
