Preheat oven to 400 degrees. Line a baking sheet with parchment paper and set aside.
In a wide shallow bowl or dish, whisk together dairy-free milk, egg and seasonings until slightly foamy. If you use boneless, skinless chicken breast tenders, you won't need to cut the chicken at all. If making "nuggets" cut chicken breast into small chunks.
Place chicken into the egg wash and be sure to turn them to ensure they are well coated with the egg wash. Allow chicken to sit in the egg wash for about 5 minutes.
On a large plate, add breadcrumbs.
Remove chicken from egg wash, one piece at a time, and dredge through the breadcrumbs, making sure to thoroughly coat each side.
Place chicken on parchment-lined baking sheet and bake approximately 18-20 minutes, until breadcrumbs are lightly browned at top/edges and chicken is cooked through.
