WOW! That was fast and turned out delicious with a less spicy rice!
I stayed out of the kitchen, so what DD#2 told me that she did was:
Put a couple of tablespoons of cream cheese in a fry-pan. Let it melt for a bit then she added the rice. Stirred the rice with the cream cheese, added some lime and sugar, let it cook for a bit, then mixed in the (prepared) beef.
She served the mixture on tortillas lightly spreaded with cream cheese.
I asked her why she used cream cheese instead of sour cream. She said (duh, Mom!
) Cream cheese is thicker than sour cream. It's like butter and holds up better when cooking.
Can I just say that I'm so proud of DD#2?
She used several of your suggestions (sugar, cream cheese, lime, and mixing the beef with the rice (instead of adding more rice) to spread the heat) to make a wonderful meal . . . and there are leftovers for her to bring to school this week.
