I wish I had read the reviews of the recipe before I made it so I could have made it more flavorful. That said, it was good. The sweet potato mixture was different, but good. My kids ate it all, so I will of course make this again! I did add cheese before adding the sweet potato layer, which did help with the flavor, but the meat mixture needs something, I just don't know what yet. I'll have to work on adding something to it, maybe taco seasoning?
