In a large bowl, mix together white wine, extra virgin olive oil, juice of half a lemon, salt, pepper, and oregano to make the chicken marinade.
First, cut chicken thighs into one and a half inch pieces. This is roughly 6 chicken cubes per thigh.
Then, mix pieces of chicken into the marinade and let them sit for 10 minutes.
While the chicken is marinating make the breadcrumb mixture.
In a shallow dish, combine panko breadcrumbs, grated parmesan cheese, oregano, salt, and black pepper to make the breading.
Next, roll about a quarter of the marinated chicken pieces in the seasoned breadcrumbs until they are fully coated.
Then, thread the chicken pieces onto skewers. Put 5-6 pieces of chicken on each skewer touching but not packed tightly. Continue until all of the remaining chicken is breaded and skewered.
Heat a large frying pan on medium heat. Drizzle enough canola oil in the pan to coat the entire pan.
Place the chicken skewers in the pan and cook until golden brown, approximately 3-4 minutes. Turn and cook until each spiedini is golden brown on all sides and the internal temperature reaches 165° F.
