You could have just said a good number of them are stored vertically so all the toppings would sloth off.
Well, that's not a convincing argument because there could be many which are not. But you can't get around the fact that nothing can ever be cooked with a pulse of heat.
You are confusing the outer radius of an explosion which passes in an instant with the fireball expansion and collapse, which at least doubles, location dependant, the exposure of an object to heat. The metal could become super heated and radiate heat for some time.
the fireball travels up into a mushroom cloud and is not present at any location for more than a second either. No explosion leaves objects super heated like an oven. They get scorched on the outside and remain cool on the inside because nothing transmits heat instantly, and the fireball does not stick around long enough to heat anything.
