Paul Nassif -- I Got to See My Boys!

Paul Nassif got to spend Saturday with his three sons ... taking them out for pizza in Bev Hills.

As TMZ first reported, a judge granted Nassif the visit Wednesday after he showed up in court armed with a report from the Department of Children and Family Services saying there was no proof he abused the kids -- despite allegations from his estranged wife, Adrienne Maloof.

The judge ordered a court-appointed monitor be present during the visit ... and we're guessing he's the conspicuous guy with the bag.
