Cut the Potatoes into wedges and set aside. Line a pan with foil and spray the foil with some cooking spray. Arrange your chicken breasts on the pan; sprinkle both sides with salt.
In large bowl, mix the mayonnaise, the dijon mustard, the olive oil, pepper and garlic.
Brush a thick coat of mixture on each chicken breast.
Add the potatoes to the remaining Dijon mayonnaise mixture and toss to thoroughly coat.
Now arrange the coated potatoes around the chicken breasts on the pan. Bake everything uncovered for about 45 to 55 minutes. About halfway through, turn everything a bit.
Notes
Note: We sometimes add chopped green onions, other veggies, different seasonings, fresh herbs.
