Cut chicken breast into ½ inch sized pieces. Season with salt and pepper.
Place seasoned chicken in a large plastic bag and add flour.
Seal the bag and toss to coat chicken completely with the flour. Shake off excess flour and set aside.
Melt 1 tablespoon butter over medium heat in a large skillet or wok.
Once butter is hot add flour coated chicken and cook until golden brown.
Remove chicken from the skillet and transfer to a plate; keep warm.
Add 1 tablespoon butter to the skillet and cook onion and mushrooms, until onions are translucent and mushrooms have released their liquid and begin to brown slightly along the edges.
Add diced ham and diced sausage to the skillet, and stir fry for 2-3 minutes to heat through.
Add asparagus and stir fry for another 2-3 minutes or until crisp tender.
Add diced red and green bell pepper and stir fry for another minute.
Add corn, peas and carrots. Stir fry until warmed through.
Add reserved cooked chicken and the cooked rice. Stir to combine all the ingredients and make sure everything is hot.
Serve garnished with a spinkle of fresh sliced scallions.
