Tostadas are a go to week night meal for me. They are so quick, easy and filling. I use flour tortillas. I dock them with a fork and spray them with cooking spray on both sides and bake them until crispy, turning them during the baking and poking any air pockets with a fork. I warm a can of refried beans for my base. I use a rotisserie chicken. I cube the chicken and put it in a non-stick skillet add your favorite taco sauce and bring to a simmer. I use Frontera brand. Top the tortilla with some beans, add the chicken and top with your favorite topping. Dinner in a flash.
