Spoon the unsweetened soy quark into a bowl. Add the chia seeds and stir everything thoroughly with a spoon or whisk, ensuring there are no lumps and the seeds are evenly distributed. Let this mixture rest on the counter for ten minutes. This allows the chia seeds to absorb moisture and gives the quark a firm structure.
Meanwhile, heat a dry skillet over medium-high heat. Toast the pecans for two to three minutes until they begin to smell fragrant and turn slightly lighter in color. Remove the pan from the heat, let the nuts cool briefly, and chop them into coarse pieces as desired.
Check whether the quark has reached the desired thickness after resting. Stir the mixture once more thoroughly and transfer it to a serving bowl.
Distribute the toasted pecans over the top of the quark. Serve immediately.
