In a medium bowl, mix together Egg (1), Frozen Spinach (2 ounce), Seasoned Salt (1/4 teaspoon), Onion Powder (1/8 teaspoon), and Ground Black Pepper (1/8 teaspoon).
Add Mashed Potatoes (1 cup) and mix until well combined. Stir in Cheddar Cheese (1/3 cup), Breadcrumbs (1/4 cup), and Fresh Chives (1 teaspoon). Mix until combined and bread crumbs have been absorbed.
Heat Olive Oil (2 teaspoon) in a non-stick frying pan over medium-high heat. While pan is heating, form 1/3 cup potato mixture into 3-inch patties about 1/2-inch thick. Place into pan as you form them.
Cook 4-5 minutes on each side, until heated through and golden brown.
Stir together Sour Cream (1/4 cup) and Fresh Dill (1 teaspoon) and season with Salt and Pepper (to taste). Keep chilled until ready to serve with cakes.
Serve sour cream dip alongside cakes. Enjoy!
