Heat olive oil in a skillet over medium heat and sauté minced garlic until fragrant.
Place the chicken breasts in the crockpot, seasoning them with salt, pepper, and Italian seasoning.
Add chopped sun-dried tomatoes and spinach to the crockpot, followed by the sautéed garlic.
Pour heavy cream over the ingredients in the crockpot.
Cover and cook on low for 6-7 hours or high for 3-4 hours.
Once cooked, shred the chicken directly in the crockpot to mix with the sauce.
Serve the Tuscan chicken over pasta, rice, or your favorite grain.
