This is such a delicious and dig-in worthy appetizer to set ou for the big game. To put it simply, this recipie is rice and cheese mixed with fresh spinach and a spicy tomato-based sauce for dunking. You can pick these poppers up with your fingers, dip, and go -- even the kids won't mind the spinach hiding in there cause of all the melty cheese.
In a large skillet, heat olive oil over medium heat. Add chopped spinach, garlic, onion, salt and pepper. Cook about 3 minutes, or until onions are translucent and spinach has wilted. Cool several minutes and place in large bowl. To this bowl, add 3 cups of pre-cooked rice, mozzarella cheese, feta cheese and eggs.
Roll approx. 2 Tbs. of mixture into a ball, and place on lightly greased baking sheet. Repeat with remaining. Bake at 350 degrees for about 20 - 25 minutes or until firmly set. Remove from oven, let cool 3-4 minutes.
While poppers are cooking, warm tomato-based sauce over medium heat on the stove top. Stir in red pepper flakes.
