Crockpot Chili with Pineapple

I thought this would be a nice weekday dinner that the kids might approve of since the pineapple lends a lot of sweetness - alas, they weren't interested but I sure liked it.

Crockpot Chili with Pineapple
1500 g beef, suitable for stewing - I use högrev
neutral oil
1 onion, chopped
1 yellow pepper, diced
1 red chili pepper, minced(or more)
6-8 garlic cloves, minced
1 dried ancho chili
400 g crushed tomatoes
2 tbsp tomato purée
2 tbsp white wine vinegar
salt
black pepper
ancho chili
cumin
coriander
1/2 pineapple, finely diced

Cut the meat into large dice and brown well on all sides in some neutral oil. Add to the crockpot. Add all the ingredients except for pineapple - I haven't given you any measurements for the spices since I have no idea how spicy you like your food. You probably do know :-)

Let this cook all day, eight hours or so on low. One or two hours before eating, add the pineapple.

Serve with tortillas or tortilla chips, sour cream, avocado, tomatoes and maybe some grated cheese. And cilantro, of course. Always cilantro!
