Notes

Other great base options instead of beans:
  • Mayonnaise or Chipotle Mayo
  • Guacamole
  • Crema Mexicana or Sour Cream
No tostada shells? No problem!
  • Make your own: If you have regular corn tortillas, you can easily make homemade tostadas by baking or frying them until crisp.
  • Appetizer style: Scoop the tuna mixture up with saltine crackers.
  • Low-carb option: For a keto-friendly, healthy alternative, skip the shell entirely and serve the tuna mixture over a bed of fresh salad greens.
