Excellent. Added some freshly ground pepper to the sauce mixture and a clove of minced garlic. Will definitely use this recipe often when grilling chicken.

I was having trouble finding a good chicken flavor that didn't require marinading for hours on end and this fit the bill perfectly! I will absolutely be making this again!

Easy Everyone liked Used worsteshire in place of steak sauce

very yummy and easy to make

We don't use steak sauce so we didn't have any so I had to use Worcestershire sauce and added a pinch of chili powder. I broiled the chicken and served with roasted red potatoes.

Wasn't that good. Sorry. Looking for a little more imaginative recipe ....I was disappointed.

Chicken was tender. I wasn't a real big fan of the mustard sauce. Too much of a tang for my taste.

The taste of the chicken was too "strong". It was edible, will not make again.

I really thought this would be great, but I was far from impressed. It was too tangy.

Absolutely love this recipe! We made it again tonight and had to scrape out our mustard bottle to get enough. Highly recommended.

It was good. Not sure what could have made it better though.

Absolutely delicious!!! I didn't have steak sauce, so I used Worcestershire sauce, which works just as well and it's just as scrumptious! Definitely a winner! And you could use the sauce probably on anything, it's so good!

Very good flavor. Also made excellent leftovers.

This is really good. I followed the recipe as written. But instead of dipping chicken into the mixture I just poured some over it. That way we had some left over to dip in. But you really don't need it as this chicken has a very nice flavor to it.

i was pleasantly surprised with so few ingredients how GREAT this recipe is! i first tenderized my chicken breasts, then marinated 6-8 hours. my low-fat mayo tended to clump, but a metal whisk took care of that in no time. other than that, i stayed true to the recipe and the chicken was bursting with flavor after marinating in the perfect ratio of ingredients. we sliced ours and stuffed them in fancy rolls for sandwiches (needed a fast meal), but this is definitely a dish that can hold it's own as a main entree with sides, and i also think it would be great sliced on top of a salad. magnifico! just wish i had leftovers...

I was looking for a marinade for grilled chicken and decided to try this. I look for simple recipes without several ingredients, and this one looked easy. I let the chicken only marinate for 2 hours, but it made the chicken very juicy and moist! I left one chicken breast out of the marinade and basted it with BBQ sauce on the grill (I was worried my picky daughter might not like this recipe), but I was very wrong! She ate 1 1/2 chicken breasts, and I was left with the dry, tough, BBQ chicken! I also didn't make extra dipping sauce, but I definitely will the next time I make this.

This was great, and VERY easy. I'll go ahead and echo everyone else...make extra sauce for dipping! I didn't, and really wished I had!

Not my favorite recipe. Too much mustard taste and too sweet. I let the chicken marinade for about 3 hours, maybe it was too much. I prefer the honey mustard for the Aussie Chicken MUCH, MUCH more.

My husband usually doesn't like chicken breasts. His comment on this one was that it was "moist and flavorful" that means it was a hit. The only thing I did differently was to baste the chicken breasts with the marinade about an hour before I put them on the grill. I will be making this again.

I made this in a skillet...still turned out pretty good. It sounds strange but it goes great with applesauce!
