I have personally made this with one goose and it made i believe 6 sandwiches
2-goose breast
4 bottles of your favorite BBQ sauce
1 table spoon of pepper and 1 table spoon of garlic or onion powder
put 3 bottles of BBQ sauce and your spices into a slow cooker along with the goose breast
cook on low for 8-10 hours
pull out pull meat apart with forks and mix some more BBQ sauce in bowl with pulled apart meat.
serve on buns and enjoy
