Knock-off Banzai Burgers

I have been fascinated recently with freezer cooking (as in making a lot of food ahead of time and freezing it and reheating it later, see for example, 30daygourmet.com).  I saw a recipe for burgers that reminded me of Red Robin's Banzai Burger, but this one had the pineapple mixed in and sweet and sour sauce.  I decided to try something a little closer to the Banzai Burger and went with the following

Knock-off Banzai Burgers

Ingredients:

1.5 lbs. ground beef

1/4 c. teriyaki sauce

1/4 c. bread crumbs

pineapple rings

lettuce

tomato

mayo

cheddar

buns

Directions:

Mix together first three ingredients, form 6 1/4 lb. patties.  Grill pineapple rings and burgers.  Serve with any or all of the other toppings.

I cooked two today, and froze the other four.  I'll comment later about how well they froze.  The flavor is good (we just ate ours plain--no cheese/tomato/lettuce/mayo).
