In a small saucepan, bring the water to a boil over high heat.
Stir in the rinsed quinoa and salt.
Reduce heat to low, cover, and simmer for 20 minutes or until all the liquid is absorbed.
Once cooked, transfer the quinoa to a large bowl and set it aside to cool completely.
Heat the oil in a skillet over medium heat.
Add the diced onion and cook for 3 to 5 minutes, until translucent.
Add the minced garlic and diced celery and cook for another 3 minutes.
Add the cooked onion mixture to the cooled quinoa.
Stir in the corn, red bell pepper, sunflower seeds, lime juice, basil, dill, thyme, and black pepper.
Mix until everything is well combined.
Taste and adjust the seasoning if necessary before using as a stuffing.
Don't skip rinsing the quinoa! This crucial step removes its natural coating, called saponin, which can impart a bitter or soapy taste to your final dish.
