Broiled Asparagus with Balsamic Aioli

1 package asparagus (I had 1 pound)
Olive oil
Balsamic vinegar
Minced garlic
Pepper
1/2 cup Mayonnaise
Garlic powder
Sea salt

Preheat oven to 500 degrees. Coat asparagus with olive oil and drizzle with balsamic vinegar. Stir in 1-2 tablespoons of the garlic. Add salt and pepper to taste. Put on foil lined pan. Cook for 10 minutes, taking out every now and then to move the asparagus around.

For the aioli: Stir in 1 tablespoon balsamic vinegar in with the mayonnaise. Add garlic powder and pepper to taste.
Dip asparagus in aioli.
