Sweet and Sour Pork

1 medium pork roast
2 cans beef broth
3 Tbsp. apple cider vinegar
1/2 tsp. ground ginger
3 Tbsp. brown sugar
2 bay leaves
1 green bell pepper, cut in strips (or 1/2 green and 1/2 red)
3 onions, sliced in 1 inch slivers
1 (16 oz.) can pineapple chunks, drained
Salt and pepper
1 Tbsp. flour (or as needed)
1/2 cup water (or as needed)
Cooked rice

Cut pork into 3/4 inch cubes, trimming all visible fat.  Brown in small amount of oil.  Add broth, vinegar, ginger, brown sugar, and bay leaves and simmer until meat is tender, about 1 hour.  In the meantime sauté onions and bell peppers until just tender.  During last 5 minutes, add to meat, then add drained pineapple and cook until pineapple is warmed.  Mix a little flour with water to make a thin paste and add to broth; simmer to thicken.  Serve over rice with soy sauce on the side.
