On a cutting board lightly pound the chicken breasts; set aside. In pie plate with fork, beat eggs with milk. On wax paper, place bread crumbs. Dip chicken in egg mixture, then in crumbs to coat both sides. Melt butter in electric skillet on medium-high heat; brown breasts, 4 at a time, on both sides, adding more butter if needed. Remove breasts to a platter and keep warm in low oven. Reduce heat in the skillet to low, squeeze juice of 1 lemon into drippings, and stir in water, bouillon, and salt. Scrape to loosen brown bits from bottom of pan. Return chicken to pan, cover, and simmer 15 minutes or until breasts are tender. To serve, thinly slice remaining lemon and arrange chicken on platter with lemon slices. Pour sauce in skillet over chicken. Garnish with parsley.
