Actually, this recipe has a lot of Dijon mustard in it as well, which goes very nicely with the lemon flavor. You can vary the amount of Dijon or garlic to your taste.The original recipe called for 6 chicken breasts, but I made it with 2 (just for my daughter and me) with the original amount of sauce. I thought this amount turned out to be perfect for just the 2 chicken breasts.(I probably like it saucy!) I'm sure you could double the recipe, although you probably wouldn't want to double the olive oil. If you are using a reduced salt chicken broth you might want to add a teeny bit salt. Cooking time includes marinating time.
