Preheat the oven to 150C/300F
In a mixing bowl, combine the almond flour, matcha powder and salt. Set aside.
Heat the honey and coconut oil together in a saucepan or in the microwave. Stir thoroughly with a whisk to mix together.
Make a well in the bowl from Step 1, and then pour in the honey-oil mixture, combining thoroughly.
Line a baking tray with parchment (baking) paper. Use 1 ½ - 2 tablespoons of the mixture for each cookie, making a small ball and placing each ball on the tray.
Pick up a generous pinch of the pistachios and push in to the centre of one of the cookie balls.
Flatten further using a butter knife and shape in to a circle shape. Tidy up cracked edges (and the overall shape) using the knife around the edge and with your fingers.
Repeat the above step for remaining cookies.
Cook for 8 minutes, then turn the tray and bake for another 2-4 minutes, until edges are a very light brown.
Remove from the baking tray immediately, being very careful not to break them. Place on a cooling rack.
Store in an airtight container at room temperature for up to 3 days. These can also be frozenm for up to 3 months.
