Mom'S Spanish Rice - cooking recipe

Ingredients

1 lb lean ground beef
1 medium onion, diced (options -- green or red pepper, garlic, celery)
2 tablespoons white vinegar
2 tablespoons brown sugar
8 ounces tomato soup
1 -2 cup water
1/2 - 1 teaspoon salt
1/4 teaspoon pepper
1 cup long grain white rice

Preparation

Preheat oven to 325\u00b0F.
Brown ground beef, break it up as it browns.
When the ground beef is taking on colour add in the diced onion and salt and pepper.
Add in any optional vegetables at this point.
When onion has softened add the vinegar and brown sugar.
Add the tomato soup and water, stir well. I start with 1 and 1/2 cups of water, you likely will need to add more as it cooks.
Adjust the seasoning if you need to.
Add in the uncooked rice and stir.
Pour into a casserole dish.
Bake in oven for 45 -60 minutes, cover for the first 1/2 hour. Check after 1/2 hour and add more water if it seems too dry.
You want it to be a bit dry in the end, soft but not mushy.
