Begin by rinsing 2 cups of sushi rice under cold water until the water runs clear, then cook the rice according to package instructions, about 20 minutes. Mix in rice vinegar once cooked.

Slice the can of Spam into ½-inch rectangles. Heat a skillet over medium heat and sauté the Spam slices until they turn golden brown, approximately 5 minutes.

Pour in teriyaki sauce and coat each slice of Spam. Simmer for about 2 minutes, flipping to ensure each side is glazed.

Lay a sheet of nori shiny-side down. Place a portion of sushi rice in the center, press down firmly, add a slice of glazed Spam, then wrap the nori around the rice and Spam.

Using a wet knife, slice the assembled Teriyaki Spam Musubi into bite-sized pieces and serve warm or at room temperature.
