Cut meat into 2-inch cubes. Wash and wipe dry Brown meat in two-thirds of the butter. Add onions and brown these too. Add wine, tomatoes (or tomato paste), salt, and pepper. Cook for about 5 minutes. Addd water. Cook until meat is tender and about 1 c. sauce remains. Cook rice as directed on package. Melt remaining butter and add it to rice. Place meat and sauce in bottom of a tube pan or ring mold. Add rice and pack lightly. Turn out onto a platter so meat is on top; the sauce will run down the sides of the rice.
