Prepare all ingredients as listed.
Preheat a grill or griddle pan over medium heat. Rub the chicken with a small amount of bbq sauce. Grill on both sides to an internal temperature of 165°F (74°C). Remove from heat and allow to rest briefly before shredding.
Set the oven to 425°F (220°C).
Lightly flour a clean work surface with whole-wheat flour and place the dough on top, coating both sides lightly to prevent sticking.
Stretch the dough using your hands or a rolling pin, keeping the thickness even and avoiding thin spots in the center.
Transfer the dough to a baking sheet, pizza pan, or pizza stone. If using a baking sheet, lightly coat it with nonstick spray to prevent sticking.
Spread the bbq sauce evenly over the dough, leaving about 1 inch around the edges for the crust. Top with mozzarella and chicken.
Bake for 10 minutes, then rotate the pizza or pan 180 degrees.
Continue baking for another 10–15 minutes, until the crust is golden brown and crispy and the cheese is melted.
In a bowl mix the beans, lemon, oil, parsley, pepper, fennel, and arugula. Set aside.
Remove from the oven and allow to rest for 2–3 minutes before slicing.
Combine all the ingredients for the lemon chia sparkling water. Stir and let sit 2 - 3 minutes for the chia to bloom.
Serve the pizza with bean salad and lemon chia sparkling water.
