I've done similar things with pan-roasted vegetables (some mix* of zucchini, onion, carrot, celery, red bell or jalapeno, mushroom (roughly that order for most-to-least used) lid is used on-and-off). I'll throw pepperoni bits in at the end to brown a bit.

If I'm lazy I'll just add sauce after plated, sometimes cheese in the pan (not long enough to cause a mess), or throw it all in a tortilla and cook it again in an old electric grill (easier to dip it in sauce instead, too).

A few times I've pre-soaked pasta noodles in a 28oz bowl, microwaved them, drain then brown the noodles a bit in the pan with everything else and transfer it back to the noodle bowl and layer in the other pizza ingredients (w/further microwaving, plate-as-lid).

* usually 2-3 things, though I've done just zucchini+sauce before
