This one in googling it - had sauerkraut in it - not exactly portuguese -- but it's got the pickled type flavor you might be going for...
Portuguese Sopa
Portuguese Sopa
4 servings
1 lb. linquica (Portuguese sausage)
4 cups sauerkraut (rinsed)
1 cup chopped yellow onions
2 cups drained garbanzo beans
1 cup chopped red bell peppers
2 cups beef or chicken stock
1 cup finely chopped or grated carrots
1 cup instant mashed potatoes (optional)
2 Tbsp. chopped garlic
1 bay leaf
1 cup burgundy wine
1/2 cup Madeira wine
1/2 cup olive oil
1 tsp. salt
1 tsp. black pepper
Peel the linguica and slice into 1/4 inch rounds. Cook in a skillet
or microwave just long enough to remove the fat. No longer than 2
minutes on high in the microwave.
In a large stock pot or soup pot add the olive oil and saute the
onions, garlic and bell pepper until the onions are translucent.
Add all the other ingredients except for the mashed potato flakes.
Simmer the soup for about 2 hours, stirring occasionally. Add the
mashed potato flakes to thicken the soup to a desired consistency.
