Heat olive oil in a large nonstick pan over medium-high heat. Season your chicken with salt and pepper, if you'd like. Add your chicken and bell pepper and cook about 4 minutes or until chicken is thoroughly cooked. Remove from pan and set aside.
Pour your water, milk, Knorr Selects and haricot verts into the same pan. Bring to a boil, then turn down the heat to medium and continue cooking for 10 minutes. Stir in lemon juice, lemon peel and basil at end of cooking.
Stir in your chicken and peppers; now it's delicious. Dig in!
