In a large skillet, over medium heat, add 1/2 tablespoon of olive oil, brown sliced sausage, about 3 minutes on each side. Remove from heat and set aside.
In a cast iron pot or large skillet, add 1 tablespoon of olive oil and sauté onions, cook for 4 minutes until it becomes translucent. Then add peppers and cook for another 2-3 minutes, then stir in paprika.
Add the chopped tomatoes, bring to a boil, the reduce heat to a simmer. Cover with lid and allow to simmer for 20 minutes stirring occasionally. Remove lid and add salt, pepper and sugar if needed. Simmer for another 10 minutes.
Tomatoes should have softened and some of the liquid remaining is to resemble a stew. Return the sausage to the pot and simmer another 2-3 minutes until the sausage is warmed through. Adjust the seasonings if needed at this point.
Serve hot with crusty sourdough bread, mashed potatoes or roasted potatoes. Garnish with parsley.
