Peel and dice apples and sweet potatoes in separate bowls.

Add butter and sweet potatoes to skillet, on medium heat. Cook 10 minutes.

Add apples, water, juice and zest of lemon, and sweetener.

Cook until soft, adding more water if needed.

Taste and correct sweetness. I like less sweet things. ***I make this dish at Thanksgiving and add a handful of cranberries when I add apples. The colors and taste is perfect! Great beside a Christmas ham as well!
