I'll try not to bore you too much, these are some of my favourites 
Mustard and Bacon Chicken ( Serves 4, 7 PPs minus the mash)
Brown 4 chicken drumsticks (you can use thighs if you prefer, just adjust the points value) in a frying pan then put in the slow cooker. Cook 4 diced rashers of bacon (fat trimmed off) in the frying pan then add 2 tablespoons of plain flour, 600ml of vegetable stock & 3 teaspoons of wholegrain mustard. Bring to the boil then pour in the slow cooker covering the chicken. Cook on slow for 8-10 hours then serve with mash.
Sausages and onion gravy (Serves 4, 8 PPs minus yorkshires)
Brown 8 beef sausages (butchers one are best) then pop in the slow cooker. Slice 2 red onions and brown in the frying pan, add 2 teaspoons of muscovado sugar and cook until caramelised. Then add 2 tablespoons of plain flour, 450ml of beef stock and 1 tablespoon of tomato puree and bring to the boil. Pour into the slow cooker then cook on low for 6-8 hours. I usually serve this inside a giant yorkshire pudding with carrots and broccoli which does push the points up but you could serve with mash or just normal yorkies 
Curry Pork (Serves 4, 8 PPs minus mash)
Pop 4 pork steaks, 1 diced onion, 1 tin of chopped tomatos, 1 tin of baked beans and 2 tablespoons of mild curry powder mixed with water into the slow cooker. Give it all a mix to combine and cook on low for 6-8 hours. Lovely with mash but is actually quite filling without any mash at all!
Tomato Chicken Pilaf* (Serves 4, 9 PPs)
Fry 4 skinless chicken breasts 'til browned on one side only then set aside. Fry 1 large chopped onion and 2 chopped garlic gloves, add a tin of tomatoes, 50g of sun-dried tomatoes, bring to the boil, add 600ml of chicken stock then pour into the slow cooker. Rinse 150g of brown easy cook rice in cold water then stir into the slow cooker. Put the chicken breasts on the top browned side up making sure they're at least half covered with the liquid then cook on high for 3-4 hours.
I also do things like spag bol, sausage casserole with dumplings, meatballs and chicken chasseaur in the slow cooker as well as others
