Preheat oven to 200°C (392°F) with top and bottom heat, or 175°C (347°F) if using convection. Grease a round ovenproof pan or casserole dish about 28 cm (11 inches) in diameter.
Open both cans of dough. Separate each can into 6 pieces and arrange all 12 pieces in the greased pan.
Spread the chunky tomatoes and their liquid evenly over the dough.
Season with salt, pepper, and chili flakes or chili powder to taste.
Drizzle lightly with Tabasco sauce if desired.
Arrange the salami on top and sprinkle the cheese evenly over everything.
Bake for 20-25 minutes until the dough is golden and cooked through.
