Open the hot dog buns and toast them in a toaster oven.

Meanwhile, melt butter in a skillet over medium heat. Once the butter has melted, add the lobster meat. Sprinkle with salt, to taste. Sauté until the lobster has been heated through, about 1 minute. Do not overheat the lobster, as it will become rubbery.

Place 1/4 of the lobster mixture in each hot dog bun.

Serve hot.
