Cook the turkey
Add the oil to a medium-sized pan over medium-high heat. Add the turkey and cook it until no longer pink.
Stir in the cumin, paprika, chili powder, garlic powder, cilantro, salt, and pepper.
Add the beans
Drain and rinse the beans completely. Mix them into the seasoned turkey. Set it aside.
Assemble the tostadas
Arrange the tortillas on a cookie sheet. Top each one with turkey mixture and cheese. Preheat the broiler to high.
Melt the cheese
Pop them into the oven until the cheese is melty and the tortillas are lightly browned. Don’t let them burn!
Remove the tostadas from the broiler. Top them with spinach, tomatoes, avocado, and lime juice to taste.
