You can make popcorn in the microwave with just kernels, a bowl, olive oil, salt, and plastic wrap. It is way healthier than bags, cheaper, and the oil makes it super crunchy.
Place kernels in bowl. Drizzle half a teaspoon of oil on the kernels and add a pinch of fine salt. Mix. Cover top of bowl with plastic wrap. Poke a couple of small holes with your fingers. Cook on high 1.5 minutes.
