In a large skillet, melt the butter over medium-high heat.
Add the shallots, and sauté for 1-2 minutes, just until softened.
Add the bacon and cook to desired crispness, about 3-4 minutes
Add the green beans, toss together until coated and cook for 3-5 minutes until green beans are softened. Remove from heat, and serve immediately.
Notes
Storage: Green beans with bacon will keep for up to 4 days in an airtight container in the fridge. You can also make the bacon the day before and add to the beans when you make the full recipe.
