Question about FB's Cashew Chicken Stir-Fry with Bell Peppers and Brown Rice Recipe

I'm looking at the ingredients for this, and i'm super confused about the chicken portion its asking for:

"4 each (500 g) boneless skinless chicken breasts, cut into bite-sized pieces"

Is this implying that each chicken breast is 500g, and it wants 4 of those? (so 2000g) or 500g total?

I'm so confused because it says it get 4 meals out of this recipe, so is each meal is about a pound of chicken??
