Heat a non-stick pan over medium-high heat and let it get good and hot. Add in the sunflower seeds and dry roast them for 2-3 minutes, until they start to turn golden brown. Add the balsamic and stir it in with the seeds until it evaporates. As soon as it is gone add the honey and stir for 1-2 minutes. Remove the seeds from the heat once they are toasted and starting to turn a darker brown. Leave them in the pan to cool.
