<human>:  I need a recipe for homemade marinara sauce. Do you have any suggestions?
<bot>: Yes, I have a few suggestions for a homemade marinara sauce. Start by heating some olive oil in a medium-sized saucepan over medium heat. Add minced garlic, oregano, and crushed red pepper flakes. Cook for about 1 minute, stirring constantly. Add canned crushed tomatoes and tomato paste. Simmer for about 20 minutes, stirring occasionally. Finally, season with salt, black pepper, and a pinch of sugar to balance out the acidity of the tomatoes. Enjoy!
