Combine flour with pepper in shallow dish. Dip chicken in eggs, then flour mixture; set aside.
Melt 2 tablespoons Spreadable Butter in 12-inch nonstick skillet over medium-high heat and brown chicken, turning once, about 5 minutes. Remove chicken from skillet and set aside.
Melt remaining 1 tablespoon Spreadable Butter in same skillet over medium heat and cook shallots, stirring occasionally, until tender, about 4 minutes. Stir in water and Knorr® Homestyle Stock - Chicken until Stock is melted. Bring to a boil over high heat, stirring frequently. Add asparagus and return chicken to skillet. Reduce heat to low and simmer until chicken is thoroughly cooked and asparagus is tender, about 3 minutes. Stir in lemon juice and serve, if desired, with hot cooked rice.
*TIP: Try using green beans, broccoli florets, green peas or sliced mushrooms instead of asparagus!
