Tomatoes on the pizza would not worry much, but if there was onion on it or a lot of garlic or a lot of cheese, then there may be a problem. However if they only ate a slice it may not be so bad. Watch for diarrhea, vomiting, abdominal pain and pale mucous membranes. If any of that occurs within the next few days, especially the pale mucous membranes (gums, for example) then they need to be seen by a veterinarian for an exam.
