We know that the TURKEY is the star of the Thanksgiving table. When a turkey is cooked properly, it’s absolutely divine. Along with the nap that follows. We also know that it’s not Thanksgiving without the supporting side dishes.

Green bean casserole is a classic Thanksgiving side. We’ve updated that classic side dish with a fresh take with real ingredients. Mixing whole ingredients like: fresh green beans, fresh mushrooms, cream, butter and organic mayonnaise together for a creamy delicious dish. Yes, we said mayonnaise, Hellman’s Organic Mayonnaise. We then top it off with the crispiest homemade fried onions. I think this updated dish might give the mashed potatoes a run for their money this year.
