Separate green bananas from the stem and wash them. Using a sharp knife, cut through or cut off the ends. Cut the side of the banana, cutting only through the skin, not deep into the flesh.
Remove the skin along the line around the banana. Discard the skin. Repeat until all the banana skins are peeled.
Bring water to boil in a large pot, add the bananas, and bring to a boil. Reduce to simmer until bananas are tender, about 20 minutes. Drain water and set aside.
While the bananas are boiling, heat oil in a large skillet over medium-high heat, add onions and cook until soft, about 2 minutes. Stir in garlic, ginger, and green onions and cook until fragrant, for about 1 minute.
Stir in tomatoes, thyme, allspice, Creole Seasoning, coconut milk, Scotch bonnet pepper and salt to taste.
Add green bananas ad and bring to a simmer. Cover skillet and allow run down to cook until sauce is thick, about 5-8 minutes.
Serve immediately. It is delicious served with Jamaican steamed cabbage or callaloo.
