Melt 2 tablespoons of coconut oil in a wok or large pot over high heat. Once the oil is melted add the popcorn kernels and cover the pot. Shake the wok or pan frequently while the popcorn is cooking. The popping noise will cease when the popcorn is done, about 3-4 minutes. Cautiously take off the cover. Transfer the popcorn to a large bowl and add the herb mixture, salt and nutritional yeast. Toss to combine.
