Preheat the oven to 285°F for 10 minutes (this step is not necessary if using a toaster oven).
Measure out & chop your nuts of choice, as needed, and then put them into a small glass bowl. Now measure out your coconut sugar, salt, and monk fruit or allulose (if using) into a separate small bowl and stir them together until well-combined.
Drizzle the date syrup over the nuts and stir everything together until each nut has at least a bit of syrup sticking to it, and then sprinkle on the sweetener mixture & salt.
Mix everything together until each nut has a thin layer of sticky sweetness on the outside, and then drop your nuts into a single layer on a baking sheet lined with aluminum foil.
Bake your nuts at 285°F (140°C) for 18 minutes, stirring them around the pan halfway through to ensure even baking. Check them again after 15 minutes in case of differences due to nut size, but 18 minutes should be adequate.
Once the coating on the outsides has solidified, but before any of the nuts begins to burn, remove the baking sheet from the oven and take off the foil, setting it on a cool surface so that the nuts won't continue to cook.
Allow them to cool for 5 minutes before enjoying, and store them in an airtight container in the fridge for up to four days.
