Peel and cube potatoes. Add to a saucepan with enough water to cover. Boil for 10-15 minutes or until softened. Drain and allow to cool completely.

Chop spinach and mix together in a large bowl with the potato. Mash together.

Grate cheddar into the potato mixture. Add cottage cheese and lightly whisked egg. Mix until thoroughly combined.

In a shallow dish, mix together bread crumbs, onion powder, salt, and pepper.

Scoop potato mixture by the tablespoon and shape into rounds the size of a golf ball. Roll into bread crumbs and set aside.

Heat oil in a large skillet over medium-high heat. Gently add each cheese ball without overlapping. Cook until golden on all sides.

Place cheese balls onto a plate lined with paper towels.

Cool slightly and serve.
