Hi Sally, it's best to use ripe plum/Roma tomatoes - they won't emit as much juice, although I have
used Campari also, and they're very juicy - basically for "Blue Cheese Broiled Tomatoes," since they don't cook very long, just enough to heat the tomatoes.
However, since the "Savory Breaded Tomatoes" do not have the seeds and pulp removed, I think you would be safe with any type of ripe tomato. With recipes that have the pulp/seeds removed, it's best to use Romas - most other types of tomatoes will collapse a lot.
