Steam the green beans and carrots together in a steamer or over the stove if you don't have a steamer.
While the green beans and carrots are steaming, place a large skillet over medium heat and add your ghee or butter. Once melted, add in garlic and onion.
When onions are about halfway translucent, add mushrooms and cook until mushrooms are soft.
Reduce heat to low and add in green beans and carrots, mix well.
Let simmer about 10 minutes.
Serve as a side for dinner and have the leftovers for lunch!
