Slow cooker tomato sauce chicken

Hi I just threw this in the slow cooker yesterday and thought it was tasty enough to share. Can be served with a side of veggies, rice, noodles, or whatever works for you

Place 8 boneless skinless chicken thighs, 1 medium onion diced, and a little water in the pot and cook until chicken is a little over half done. Add a large 795ml can of diced tomato, 100g of diced green pepper, 50g sliced mushroom, 1-2 minced cloves of garlic, 2 tbsp oregano, black pepper and salt free mrs dash to taste.
