I also like to use what I have on hand. In the freezer I had a boxed package of pie dough.
I started with some left over rice then I topped it with carrots (cut into cubes).
In the last couple of minutes I poured about 3 tablespoons of melted butter over the top to give it a browning agent.
I thought the pie was pretty good but it was a bit dry. My son didn't like the rice in the pie. He said it wasn't what he expected when he cut into the pie.
But this is a quick easy dinner and it was different than the regular rice and chicken or rice and pork.
