Place the popcorn kernels and oil in a large microwave safe bowl and stir until each kernel is covered with oil. Cover the bowl with a vented lid. Alternatively, cover the bowl with parchment paper and secure with a rubber band, then poke a few holes with a knife.
Microwave on high for 2 minutes or until the popping slows down to 1-2 seconds between pops.
Carefully remove the bowl from the microwave. Let cool slightly, then toss popcorn with your preferred seasoning (or try all three of them!)
