Toss the mashed potatoes, diced onions, and leftover chopped veggies in a big bowl. Stir everything around until it's all evenly combined.
02 -
In a large frying pan set over medium heat, melt the butter and olive oil together. Once the mixture is bubbling and hot, you're ready to go!

Spread the potato blend into a single, flat layer in your pan. Leave it alone to cook for 10 to 15 minutes, long enough to form a crispy, golden layer on the bottom.

Flip the mixture gently (don’t stress over it breaking!) and let it cook another 5 to 10 minutes until both sides are perfectly golden-brown and crunchy.

Sprinkle on some salt and pepper until it tastes just right. Share while it’s still fresh and crispy!
