Cook ground chicken with onion and seasonings in a skillet until the meat is fully cooked. Drain meat if needed.
Add in potatoes, tomatoes, plums, and olives and stir to combine all ingredients.
Bring the mixture to a boil then reduce to a simmer.
Keep the skillet covered and cook for 10 minutes until the potatoes become tender.
Uncover the skillet and let the liquids evaporate. Take off from the stove and let it cool down a bit.
Arrange tostada pieces and lettuce on a serving platter, and place chicken mix, cheese, green onion, and cilantro on top of the lettuce.
Notes
Different Meats: While our recipe calls for ground chicken, feel free to get creative and try different meats to suit your taste preferences. Ground turkey or ground beef can be excellent alternatives.
Taco Seasoning: For an extra burst of flavor, consider adding in some homemade taco seasoning to the chicken. It's a simple process that allows you to adjust the spice level and tailor the flavors to your preference.
Taco Bowls: If you want to switch things up and add a fun presentation element to your meal, consider making taco bowls instead of using tostada shells. The taco bowls provide a crunchy and edible vessel for your salad, adding a delightful twist.
