Place the chicken, salt, pepper, and water in the crockpot (slow cooker) and let cook until the chicken is tender, about 4-5 hours on high or 6-8 hours on low.
Heat the sun-dried tomatoes, artichoke hearts, lemon juice, and olive oil (I just use the oil that the sun-dried tomatoes come in) in a skillet over medium heat until everything is warmed through. You can cut the artichokes into smaller pieces if you want, but it's not necessary.
Move the chicken to the skillet and stir everything together. The chicken will break up into smaller pieces while you stir, no need to cut it.
