Thank you so much for adding low carb recipes!
Going to try this tonight!
You’re very welcome! Hope you love it!
Unfortunately, the orzo burned to the liner bottom. But I was able to eat most of it and I liked the taste!
I know what I did wrong and will try again.
I’m glad it was salvageable!
Made this last night, and we both thoroughly enjoyed it! This recipe is a keeper.
Thanks for the 5 stars Jeannie!
