Rinse the sunflower seeds and soak in water in the fridge for 8 hours or overnight. Once soaked, rinse several times (this will help remove some of skin on the seeds).
Combine drained sunflower seeds with lime juice, 4 tbsp/60ml olive oil, and 1/2 cup/120ml fresh water in a blender.
Puree on high speed until very smooth.
Add in chipotles, brown sugar, garlic, 2 tsp/4g cumin, 2 tsp/4g coriander, 1 1/2 tsp/3g smoked paprika, and 1 tsp/6g salt.
Puree until smooth. Add more water to reach desired consistency.
Dressing can be made and stored for up to 1 week in the fridge. For an even creamier dressing, add oat or soy milk in place of ½ cup/120ml water.
Left thick, dressing can be used as a dip for vegetables and chips (or even taquitos) or a spread in sandwiches and wraps. Thin with water to drizzle on salads and grain bowls, fajitas, or other proteins.
