Easy Pork Roast

1 (4 lb.) pork shoulder roast
2 (16 oz.) cans cannellini beans
1 (12 oz.) can beer
1 (28 oz.) can stewed tomatoes, drained
2 large onions, coarsely chopped
10 shallots, peeled
10 cloves garlic, peeled
Salt and black pepper to taste
2 bay leaves; 3 springs fresh rosemary

Preheat oven to 275 degrees. In a large skillet over medium-high heat, brown the roast on all sides, about 10 minutes. Place roast into a large roasting pan. Pour beans, beer and tomatoes over roast. Arrange onions, shallots, and garlic, bay leaves and sprigs of rosemary around the roast, and season with salt and pepper. Cover, and bake for 4 hours. Raise the temperature to 425 degrees, and roast 1 hour more.
