How to make
In a large bowl, mix all of the products and knead the dough.
Shape it into a roll with your hands. Wrap it in cling film and leave it in the freezer for 15 minutes.
Take it out and cut it into circles. Place a walnut on each piece.
Arrange them in a tray lined with baking paper and bake the savory biscuits for 15-20 minutes in a preheated oven at 340°F (170°C).
The savory biscuits with cheddar, olives and ricotta are ready.
