Cut chicken breasts into 1-inch wide strips.
In a shallow dish, combine cooked quinoa, garlic powder, onion powder, paprika, salt, and pepper.
In another shallow dish, beat the eggs.
Dip each chicken strip in the beaten egg, then dredge in the quinoa mixture, pressing to adhere.
Heat olive oil in a large skillet over medium-high heat.
Carefully place chicken tenders in the hot oil in batches, ensuring not to overcrowd the pan.
Cook for 5-6 minutes per side, or until golden brown and cooked through (internal temperature reaches 165°F/74°C).
Remove chicken tenders from the skillet and place on a paper towel-lined plate to drain excess oil.
