Generously smear the bottom and sides of a mixing bowl with half of the dressing.
Throw in the lettuce, beef tongue, tomato wedges and onion slices.
Toss everything together lightly but thoroughly until everything is moistened. Toss, NOT mix.
If the salad looks like it needs more dressing, add the rest of the Caesar salad dressing and toss again. Still too dry? Add another tablespoon of dressing and toss once more.
Add the croutons and give the salad a few more tosses.
Taste the salad. Add salt or pepper, or both, if needed.
Serve the beef tongue salad with herbed croutons immediately.
