Tip #1: As the beans cook, they will turn into a darker more olive green color. This lets me know it's almost done.
Tip #2: Add some fresh basil for some extra flavor. It tastes great!
Tip # 3: The reason for crushing the garlic is that it lends a good overall flavor without overpowering the beans. If you were to mince the garlic, the aroma would be stronger. But prepare it however you want it, that is the joy of cooking!
Tip #4: Keep an eye while cooking these and add more water as needed to prevent burning.
