1. Preheat the oven to 220°C (425°F).

2. Finely chop the bell pepper and sauté it in butter with the ground meat and taco seasoning until it's nicely browned.

3. Add the corn kernels, chili paste (sambal oelek), and tomato sauce to the pan. Let the mixture cool down.

4. Roll out the pizza dough on a floured surface and spread the cooled meat mixture along the center of the dough in a long, thin line.

5. Roll up the dough tightly and shape it into a ring, making sure to press the edges together to seal the filling inside.

6. Place the ring on a baking sheet lined with parchment paper, cut small slits along the top, and brush with a beaten egg. Sprinkle shredded cheese evenly over the top.

7. Bake the ring in the preheated oven for 20 minutes, or until it's golden brown.

8. Mash the avocado in a bowl, removing the pit, and finely chop the onion, chili, and garlic. Combine these ingredients with the mashed avocado and season with salt to taste.

9. Cut the baked ring into bite-sized pieces and serve with the freshly made guacamole.
