Rinse and cut each potato into 8-12 pieces (smaller pieces are great for small children). Dice onion and pepper. Mince garlic. Place aside, separately.
Add 2 tablespoons olive oil to a large skillet over medium. Once hot (You can check by adding a few small drops of water to skillet. If it sizzles and pops, the skillet is hot), add potatoes, pepper and onion. Saute for 6-7 minutes, allowing potato to soften.
Meanwhile, cut zucchini into 1/2 inch thick rounds and then into half moons. Slice mushrooms. Add zucchini, mushrooms and garlic to skillet. Stir to combine, cover and continue to cook for 2-3 minutes. Stir halfway through cook time.
Pour into a bowl, cover and set aside.
Add remaining olive oil to skillet and heat over medium. Slice sausage into thin rounds; 1/2 inch thick. Add to hot skillet and cook for 5-6 minutes. When done, sausage should no longer be pink.
Add veggies back to skillet, season with salt, pepper and fresh parsley. Stir together and heat through; 2-3 minutes. Serve with fruit.
