A grill-top pizza oven

Here in Singapore, we went into full-on lockdown in 2020. We were allowed to go to the grocery store, but otherwise we could not go anywhere.

And I just got a hankering for some pizza. But the ovens here are pretty small, like the size of a microwave. I tried to make a pizza on my gas braai by sliding it directly on to the grid, but it was just all right. I wanted that leopard-spotted bottom, and the charred bubbles on the crust. I saw online.
