Spray a baking sheet with olive oil cooking spray. In a medium saucepan, heat olive oil over medium-low heat until just warm, about 1 minute. Add garlic; sauté for 1 minute.
Add tomato sauce, salt, sugar and red pepper flakes; stir well. Heat until sauce begins to bubble. Reduce heat to low; simmer 10 minutes. Remove from heat.
On a medium plate, combine panko, garlic powder, oregano, salt and pepper.
Place flour on small plate. Coat each stick in flour. Shake off excess; dip in egg. Dip sticks in panko mixture. Place sticks on baking sheet 2 inches apart. Spray tops with olive oil cooking spray. Place baking sheet in freezer for 1 hour; refrigerate sauce.
Preheat oven to 400 degrees 15-20 minutes before serving.
Remove baking sheet from freezer; place in oven. Bake for 8-10 minutes, until sticks are just heated through, not melted. Remove from oven.
Remove sauce from refrigerator. Microwave for 1-2 minutes until warmed through. Serve with sticks.
