How to Make It
Combine first 10 ingredients in a large bowl. Stir in 1/4 teaspoon salt and 1/4 teaspoon pepper. Divide and shape mixture into 8 (1-inch-thick) patties (about 1/2 cup each).
Heat 1 tablespoon oil in a large nonstick skillet over medium-high. Add patties to pan; cook 4 minutes on each side or until browned and crisp. Remove from heat.
Combine remaining 1 1/2 teaspoons oil and spinach in a medium bowl; toss gently to combine.
Combine remaining 1/8 teaspoon salt, remaining 1/4 teaspoon pepper, mayonnaise, sour cream, and paprika in a bowl, stirring with a whisk. Divide spinach among 4 plates; top evenly with patties and mayonnaise mixture. Serve immediately.
