I don't think rice does well in the crock pot. It gets gummy and doesn't cook fluffy.
I made beef fajitas last night, grilling a Flat Iron Steak. I had never heard of that before, but Kroger had it on sale last week. It is a very good, tender, juicy and flavorful cut of meat. I sauteed red,green and yellow bell peppers along with a sweet onion as well. I made a corn and black bean dish, seasoning with cumin, garlic, onion and the 3 colors of peppers. I have enough left over to make quesadillas for supper with the corn and black bean dish and a salad on the side. Here's a link that tells about the Flat Iron Steak:
