Pineapple Burgers

Directions

1. 1
   Split and form the ground beef into eight equal patties.
2. 2
   Seal two patties together with a pineapple ring inside.
3. 3
   Grill until done (can also be done in a broiler).
4. 4
   While the burgers are grilling prepare the sauce.
5. 5
   Combine the ketchup, brown sugar, and mustard together on the stove until warm (or you can mix and microwave it).
6. 6
   You just want to warm it up and get the brown sugar smooth.
7. 7
   If desired, put one slice of cheese (I love a white cheese -- swiss or provolone) on each burger and melt.
8. 8
   Serve each burger with some of the sauce spooned over the top.
9. 9
   Feel free to adjust the amounts of the ingredients in the sauce to suit your taste -- it's been so long since I've actually measured it, I usually make it then taste and adjust.
10. 10
    You want it sweet with a slight tang.
