I browned 1/2 lb of ground beef with 1 chopped onion, because that's what I had on hand, but next time I will probably do 1-1/2 lbs of ground beef. It just needed more meat. I then drained the meat and put it back in the skillet. Next I added beans; I used 1 can of drained kidney beans and 2 cups of pinto beans that I had already cooked previously. You could use any type of beans you like. Then I stirred in 1/4 cup taco seasoning and tossed in some frozen corn (I just eyeballed this...use however much you like. I'm sure canned corn would work also). I heated it through, then transferred the mixture to a greased 9 x 13" pan and sprinkled cheddar cheese on top. Next I mixed up a batch of cornbread mix--the amount that would normally go into an 8 x 8" pan--but instead I spread it over the top of the meat/beans mixture. I use a gluten free recipe, but any will work!
After that....I baked for about 30 minutes at 375 degrees. To check for doneness, insert toothpick or knife in center to make sure cornbread topping has fully baked.
The bottom layer on this was just too thin, which is why I want to add more to it next time.
So there you go...a yummy frugal meal for you to try out!
Blessings to you and your family!
