Made this tonight, used 1 lb ground beef in between the last layer of peppers and cheese. Unfortunately, there is no amount listed for the milk. I guessed and used about 1.5 cups. We thought it came out well and tasted ok

Hi Pattie! Thank you so much for making the Chili Relleno Casserole. I totally had overlooked the milk quantity! Thank you for letting me know! I use 2 cups of milk, so 1.5 cups was a great estimate. I like the idea of adding ground beef to the dish. Sounds very tasty! Cheers! Laura
