Preheat oven to 350. Grease a large 9×13 baking dish with 1 Tbsp of coconut oil. Heat a skillet over medium-high heat. Warm the other 1 Tbsp of coconut oil in the skillet. Add the mushrooms and garlic and sauté for 3-5 minutes until fragrant and softened. Mix all the ingredients together in a large bowl. Or heck, throw convention out the window, spare yourself another dirty dish, and just mix them all together in the baking dish. Bake for 20 minutes or until a toothpick inserted in the middle comes out clean. Top with fresh tomato slices.
