First, rinse about 1 pound of fresh green beans under cold water to remove any dirt. Trim the ends for a clean presentation; lay the beans flat on a towel to dry.

In a large skillet, heat 2 tablespoons of olive oil over medium-high heat until hot, shimmering but not smoking, for about 1 minute.

Add the green beans to the skillet in a single layer and cook undisturbed for 5-7 minutes until they start to blister.

Reduce heat slightly, add 3 minced garlic cloves and 1 tablespoon of miso paste, stir gently, and cook for an additional 1-2 minutes until garlic is fragrant.

Remove from heat, season with salt and freshly cracked pepper to taste, stir to ensure well-distributed seasoning, and serve warm.
