Papaya is a healthy fruit but honestly, I haven't tried preparing it as smoothie. I just normally eat it directly if ripe or eaten as part of some soup. I think children will enjoy this way of preparing papaya too. Pizza is one of my favorite snacks too. You can make the dough by yourself or buy ready-made crust at supermarkets. Air fryers are really useful especially when you are in a hurry and if you don't need to prepare anything fancy. Yum!
