Quick Tortilla Pizza with Mushrooms & Bell Pepper

Preheat the oven to 180 °C top/bottom heat.

In a small bowl, mix ketchup, olive oil, pressed garlic, oregano, and pepper into a smooth sauce and set aside.

In a large pan, melt the butter over medium heat. Place one tortilla in it, sprinkle evenly with grated Gouda, and place the second tortilla on top. As soon as the bottom side is golden brown and crispy, carefully flip the tortilla sandwich and briefly fry the other side until the cheese inside melts.
