Place chicken stock in a medium saucepan and bring to a boil. Lower to a simmer and add chicken tenders. Make sure tenders are completely covered with chicken stock. If not, add more stock or water. Cook until chicken is fully cooked, about 15 minutes. Remove from stock and discard the stock.
While the chicken cooks, place the rest of the ingredients in a food processor and blend until basil is in small pieces. Set aside for next step.
Place cooked chicken in a bowl of a stand mixer. Using a paddle attachment, beat chicken on low to shred the chicken. Once shredded, add in the blended dressing and mix on low to combine with the chicken.
Remove from bowl and make sandwiches or store in refrigerator to enjoy later.
