hecks yes too all that.I have made and enjoyed several "salad pizzas". A caesar salad on top of baked pizza dough (with melted cheese and dressing as the sauce) is both legit and filling.
Another is a BLT pizza with mayonnaise spread on after the dough and cheese are baked. In other words, bake dough with cheese, spread mayonnaise, top with chopped bacon, lettuce (sometimes dressed in ranch), and tomatoes.
The combination of a warm dough/crust with cold salad is suprisingly good, especially on a warm day.
