This had got to be my best Thanksgiving leftovers repurposing idea yet. Admittedly, this is a little weird considering flammkuchen comes from Germany/France where they do not celebrate Thanksgiving.
So call them Thanksgiving Leftover pizzas if you like. The ones pictured have mashed potatoes, mashed sweet potatoes, roasted Brussel sprouts, shredded roasted turkey and cranberry sauce. For extra crunch, I sprinkled some raw walnut pieces over the tops.
You can get creative with whatever savory leftovers you have in your fridge. String beans, creamed corn, stuffing all would work well. Sprinkle nuts or cheese over the top if you like. For a breakfast version, crack an egg on top before baking.
