If you don't find smoothies very filling, then why not try a smoothie bowl that is loaded with toppings. There are so many different flavour combinations.
Put all of the ingredients in to a blender and blend until smooth.
Pour in to a bowl and add toppings.
Notes
If you don't have frozen fruit, then you can add ice cubes to the blender instead.
Try to make the smoothie from fresh. However if you want to prep it in advance, then you can put everything except the liquid in a freezer bag and freeze until you need it.
Don't add too much liquid, as you want to smoothie to be nice and thick, so the toppings don't sink. It should be the texture of soft serve ice cream.
