Add the onion, bell peppers, garlic, JUST 1 cup of the broth and JUST 1/2 teaspoon of the salt to a large pot over medium heat. Once it begins to bubble all over, cook for about 8 minutes until the veggies are tender and all the broth is gone. You want the broth gone before adding the wine, this will keep the sauce thick and not watery at the end.
Add the potatoes, tomatoes, pepper, another 1/2 teaspoon salt and the remaining broth. Start out with 1 1/2 cups and add more if desired or needed to cook the potatoes. I used the full 2 cups because my potatoes needed it and I wanted it a bit saucy. Stir well and turn the heat to high. Once it comes to a boil, cover and lower the heat to medium-low. Cook for about 15-20 minutes until the potatoes are tender, but not mushy. Taste and add any more seasoning if needed. Serve immediately either as is or over white rice.
