In a medium bowl whisk together the egg and 1 tbsp lemon juice. Set aside.
In a separate medium bowl mix together the flour, paprika, garlic powder, and pepper. Put this mixture into a plate.
Dip each side of the chicken breast in the egg and lemon mixture then dredge in the flour mixture. Repeat for each chicken breast.
In a large skillet over medium to high heat melt the butter until it is slightly golden brown. Add each chicken breast in a single layer. Fry uncovered for 3-5 minutes until golden brown. Flip and fry until that side is golden brown. Reduce the heat to low.
In a small bowl put in the water, bouillon cubes, and 2 tbsp lemon juice. Microwave until the bouillon cubes are soft and easily break apart with a fork. It will take 1-2 minutes.
To the skillet, add the bouillon mixture, capers, garlic, and the lemon zest.
Cover and simmer until the chicken is done and no longer pink inside. It will be about 5 more minutes.
Cook the pasta according to package directions. Save some of the pasta water before draining.
Remove the chicken breasts from the skillet and add the pasta to the remaining sauce in the pan. Add in the pasta water and toss to coat the pasta.
To serve, put some pasta on a plate and top with a chicken breast. Enjoy!
