Pound chicken to about 1/2 inch thickness, and cut each chicken breast in half.
Season both sides of the chicken with kosher salt and pepper.
Slice a few VERY thin slices from the lemon, then squeeze the juice from the lemon, and set aside.
Boil the water and dissolve the bullion in the water. Set aside.
In a bowl, beat an egg with 1 Tbsp of the lemon juice.
In a bowl or dish, mix the flour with the paprika and garlic.
Melt the butter in a large pan over medium-high heat.
Drench the chicken in the egg mixture, and then generously coat it in the flour.
Once the butter is melted and bubbly, place the chicken in the pan, browning both sides.
Pour the chicken broth, remaining lemon juice, and lemon slices into the pan and reduce heat to low.
Cover and cook for about 20 minutes.
