Fantastic! I've been on the hunt for easy and cheap with #3 due to arrive soon. I want to keep the crazy to a minimum so this is perfect! And you caught me on grocery day, so I can pick up the canned chilis. (Everything else is something I normally buy too) Perfect!

Thanks for sharing!!!!
Do we cover the pyrex dish with foil or just leave it uncovered when we put it into the oven? Thanks, I am trying this while subbing gluten free flour…I hope it turns out ok!
Hi Sher! I leave it uncovered, I like it to get a little crispy on top.
Thanks! I made it using a gluten free Bisquick mix and it was a hit. All four of us gobbled it up. I’m sure the texture of ours was maybe different than if we would have used regular flour….but it tasted really good. We are making it again tonight!
