Cut a piece of prosciutto to fit the center of the dough triangle, stopping an inch before the point. Add 1 tbsp of drained fire-roasted tomatoes across the wide edge at the top, then sprinkle 1 tbsp of grated cheese over the tomatoes. Spread 1 tsp of humus over the cheese. Starting at the wide edge, stretch dough over stuffings, and roll crescent to the point. Brush top of roll with olive oil and place an additional Tbsp of grated cheese on top. Repeat with the rest of the crescent dough triangles.
