To make your own toasted pecans: Preheat oven to 180C. Add pecans to a lined tray. Roast for 8-12 minutes, tossing halfway. Be careful not to burn!
Melt the tahini and butter together.
Add the pitted dates and pecans to a food processor and blend until a sticky dough forms.
Press the date-pecan mixture into a lined baking tin.
Melt the dark chocolate and pour over the top, spreading evenly.
Sprinkle with flakey sea salt.
Refrigerate until set, then cut into bars.
