Step 1: Prep the Chicken
Place the chicken breasts in the base of your slow cooker. If they’re thick, you can pound them slightly to ensure even cooking. Season both sides with salt, pepper, oregano, basil, and red pepper flakes.

Step 2: Add the Veggies and Aromatics
Layer the diced tomatoes, olives, red onion, and garlic over the top of the chicken. Don’t stir—just let everything settle so the chicken stays covered.

Step 3: Set and Forget
Cover the slow cooker and cook on low for 6–7 hours or high for 3–4 hours, until the chicken is fork-tender and fully cooked through. Avoid opening the lid too often—this helps maintain even heat and keeps the chicken juicy.

Step 4: Finish and Serve
Once done, give the sauce a gentle stir. Taste and adjust seasoning if needed—sometimes a small pinch of salt at the end really lifts everything.

Spoon the chicken and sauce over cooked couscous or quinoa. Garnish with freshly chopped parsley just before serving.

Enjoy immediately, or let it cool and store for meal prep throughout the week.
