Combine the Parmesan, garlic salt, paprika, pepper, salt and turmeric in a small bowl. Combine the popping corn and melted butter in a large pot. Cover and cook over medium heat, shaking the pot with increasing frequency as the popping increases. Continue until the popping is reduced to a couple of seconds between pops, then remove from the heat and transfer the popcorn to a large brown bag. Drizzle the popcorn with the olive oil and sprinkle about 3 tablespoons of the seasoning into the bag. Shake up the popcorn. Sprinkle with additional seasoning to taste and serve warm.
