Keep in mind it can only be stored for a few hours though, as after that it will begin separating.
It's a cinch to whip up and will really add pizazz to your meal. Try spreading any leftover sauce on your sub sandwiches, that's fantastic too.

4 cloves garlic, minced
2 egg yolks
1 cup extra virgin olive oil
2 teaspoons lemon juice
salt to taste
ground black pepper to taste
In a medium bowl, beat egg yolks well with a wire whisk. Stir in garlic. Gradually add oil in a thin stream, beating constantly until light and creamy. Season with salt and pepper. Stir in lemon juice. Refrigerate.
Note: You can also make this in a food processor.
