@ddljohn-- Rice macaroni is not tasteless, it tastes good. I love using it instead of Asian rice noodles in soups and cold pasta salads. Rice noodles work great in vegetable soups.
I also make a dish called Koshary with rice macaroni. I learned about this dish from my Egyptian friend. It's made with macaroni, rice, lentils and tomato sauce. It's delicious and also vegetarian!
