This recipe was written on a sheet of lined paper and found in a large collection, date unknown. All the ingredients are listed along with sparse directions, I believe you pop this in the oven and heat until dish is hot (since the rice is already cooked). Recipe is typed below along with a scanned copy (spelling errors corrected).

4 cans green chilies – mild or hot (drain)
