Hello. This looks great! I am teaching my son to cook and this would be perfect. We use a lot of your recipes...Is there a way to print this one (I don’t see it)? Thanks!

Hi Theresa

You bet. There is a PRINT button located at the bottom of the recipe-if you click the JUMP TO RECIPE at the very top-it will automatically take you to that print button!

Thank you!

Linda, if I use chicken breast in place of the beef, would the free style points change? Are there any other ingredients I would need to alter if I used chicken breast? Peggy

Hi Peggy,

The point value would be 2 freestyle smart points per serving, if you substituted the beef/steak for skinless, boneless chicken.

Is there a substitute for Sriracha sauce that you would recommend?

Hi Sherry,

You could substitute it for chili paste, tabasco sauce, chili flakes, or cayenne pepper.

Thanks so much, Linds
