Line 2 baking sheets with parchment paper and divide the rolls in half.
Cover with plastic wrap and thaw overnight in the fridge or for 2 hours at room temperature.
30 frozen dinner rolls
In a large skillet, combine onion, garlic, oil, chili powder, salt, and pepper and mix well. Heat over medium heat until onions are tender, about 5 minutes.
½ cup onion, 2 tbsp. olive oil, 2 tbsp. minced garlic, ½ tsp. chili powder, ½ tsp. black pepper, ½ tsp. salt
Add spinach and continue to heat for 4-5 minutes or until wilted and soft. Remove from heat and let stand to cool.
16 oz. fresh spinach
In a separate bowl, combine mozzarella, feta cheese, and eggs and mix well. Fold in cooked spinach.
8 oz. shredded mozzarella cheese, 2 eggs, 8 oz. crumbled feta cheese
Drizzle each dough ball with oil, coating on all sides.
Use a 1/2 cup measuring cup to press the bottom into the dough, creating a flattened divot-like bowl.
Divide the spinach mixture evenly into each cavity and bake at 275 for 15-18 minutes or until golden brown. Cool slightly before serving warm.
Notes
Frozen Roll Tip: I thawed my rolls overnight in the fridge covered in plastic wrap. I knew that would ensure they were thawed completely vs. timing them for 2 hours.
