Soak and wash beans thoroughly. Place beans in a pan or kettle, cover with water and salt. Soak overnight. In the morning, drain, add 2 quarts of water. Bring to a boil, and simmer slowly 2-1/2 or 3 hours.
In a skillet, sauté onions and garlic with the sausage, until the sausage is browned. Drain off excess grease and add the contents to bean pot with the tomatoes, lemon juice, and spices. Simmer another 30 minutes. Serve with crackers and green salad.
