Preheat the oven to 180 degrees C. Grease a 25cm pie dish.
Cook beans and rice according to packet directions. Saute onions in butter until golden. Beat milk into eggs then stir in the cheese, salt, tarragon and Worcestershire sauce. Fold in cooked onions, rice and beans.
Pour in the egg mixture into the prepared pie dish. Bake for 30 minutes in the preheated oven or until set and edges are brown. Let cool for 10 minutes before slicing into wedges to serve.
What temperature should this be baked at? I'm baking a double batch with paprika as no tarragon at 180C. Plus I added some diced sweet potato. I have a hungry family of six to feed! So far so good - 23 Feb 2014
