Boil the tempeh for 5 minutes to remove any bitterness. This also helps soften the tempeh so that it absorbs the sauce better.
If using fresh green beans - rinse, remove stems and cut into 2 inch pieces. In a small pot with about 1-2 inches of water, boil green beans for 5 minutes. You can also use a steamer basket in a small pot with 1 inch of water, bring to a boil and steam for 5 minutes.
In a large deep skillet, heat olive oil over medium heat.
Add onion and sauté 2 minutes, add tempeh to skillet and cook 2-3 minutes more or until onion is softened. Add garlic and sauté about 30 seconds.
Now add vegetable broth, coconut aminos, maple syrup and green beans to the pan. Heat to boiling, then reduce to a simmer and cook 15 minutes.
Blend cornstarch and 1/4 cup of cold water in a small mixing bowl. Stir into the tempeh and green beans until sauce begins to thicken.
Add additional vegetable broth and coconut aminos to obtain desired consistency and flavor.
