1 medium onion - chopped coarsely
3 medium tomatoes, quartered
4 tablespoons tomato paste, dissolved in 1 cup water
3 tablespoons fish sauce
1 large bell pepper, sliced into strips
1 medium potato, diced
2 medium carrots, in 1 inch rounds
3 bay leaves
Salt and pepper to taste
In a 4-quart crockpot combine all but last two ingredients. Set on low for 6-8 hours. In last hour of cooking, add bay leaves and season with salt, pepper or additional fish sauce.
* I have found that the "last hour of cooking" (when you can add the spices and vegetables for additional flavor) is actually a great time to cook your accompanying white rice.
