1. Preheat the oven to 350 degrees Fahrenheit.
2. In a large saucepan, bring the broth to a boil. Add the grits and stir well. Reduce the heat to low and cover the pan, allowing the grits to cook for 5-7 minutes or until they are tender. Stir frequently to prevent clumping.
3. Add the butter, cheddar cheese, parmesan cheese, half of the smoked gouda cheese, heavy cream, hot sauce, black pepper, garlic powder, and salt to the grits. Stir until the cheese has melted and all of the ingredients are well combined. Adjust the seasoning to taste.
4. In a separate pan, add the collard greens and cook them for several minutes until they are just wilted. Drain off any excess liquid and set the greens aside. Or use leftover Collard Greens.
5. Add the cooked greens to the grits and mix well.
6. Pour the grits and greens mixture into a casserole dish and spread it out evenly.
7. Top the casserole with the remaining smoked gouda cheese and chopped bacon.
8. Bake the casserole for 15-20 minutes or until the cheese on top is melted and bubbly.
9. Remove the casserole from the oven and allow it to cool for a few minutes before serving.
