Place bacon in a large, deep frying pan. Fry over medium high heat until almost crisp. Stir in onions and garlic, cook further 1 minute.
Stir in beans and add water.
Let the beans cook until the water has evaporated and the beans are tender. If the beans are not tender once the water has evaporated, add a small amount more water and cook further until tender. Season with salt and pepper to taste.
