Roast Beef Sandy with Blue Cheese Aioli

At Caputos, our local grocery, they have these wonderful little sandwich size tomato focaccias; if you can't find these, just use some other sort of very flavorful bread (for example, a kalamata olive bread). The homemade aioli makes the sandwich! I am only able to make aioli using a mini food processor- the instructions call for a mortar and pestle so if you know how to do it "old school", more power to you!

For the aioli:
2 egg yolks
1 garlic clove
2 T lemon juice
1/4 t salt
1 t Dijon mustard
2/3 cup grapeseed oil
1/2 cup blue cheese or gorgonzola crumbles
1/2 t whole grain mustard
2 T chopped, fresh parsley

Put the egg yolks, garlic, lemon juice, salt and dijon mustard in a mini food processor; process until combine. Add grapeseed oil (I do this through the top of the processor- there are two very small holes) very, very slowly- process until emulsified. Transfer the aioli to a bowl and add gorgonzola or blue cheese crumbles, the whole grain mustard and parsley.

For the sandwich:
yummy bread or focaccia
roast beef, sliced thin from the deli
sliced red onion
blue cheese aioli
arugula
anything else that grabs your fancy (tapenade, tomato, artichoke spread etc.)- I didn't use any of these but I just might!
