Step 1

Bring water, quinoa, and 1/2 of the taco seasoning mix to a boil in a saucepan. Reduce heat to low, cover, and simmer until quinoa is tender and water has been absorbed, about 15 minutes.

Step 2

Mix chicken and remaining taco seasoning mix together in a bowl; let sit for chicken to season, about 10 minutes.

Step 3

Heat butter in a skillet over medium heat; cook and stir chicken until no longer pink in the center, 5 to 10 minutes. Place chicken and quinoa in a bowl and place in freezer until cooled, about 5 minutes.

Step 4

Combine avocado, red onion, celery, spinach, carrot, red bell pepper, yellow bell pepper, cucumber, and jalapeno peppers in a large bowl; add chicken-quinoa mixture and salsa and mix well.
