Divide chicken and veggies into 4 quart size or 2 gallon size ziplock bags.
In a small bowl, Whisk the olive oil, garlic, Italian seasoning, paprika, salt, and pepper. Divide marinade equally into the ziplock bags, seal and shake to fully coat the chicken and veggies. Freeze for up to 2 months.
To cook, Heat skillet to medium-high heat and pour 1 bag into skillet and saute for 10-15 minutes or until tender and cooked. Alternatively, Pre-heat oven to 425F. Line a sheet pan with foil and pour chicken and veggies onto foil and roast for 15-20 minutes.
