On a floured working surface, use a rolling pin to roll pizza dough into a rectangle shape about 14" x 10" (35 x 25 cm). Transfer the dough to a baking sheet lined with parchment paper.
Spread the pizza sauce onto the dough, garnish with tuna and broccoli. Cover with grated cheese and add bacon bits.
Cook in the middle of the oven for 10 to 12 minutes.
