I use one that I’ve pinched and adapted from one of the above threads.
I generally multiply up to 1 or 2 kg mince, as it’s pretty much the same effort, and does multiple meals.
500g mince
1 small Onion
3 garlic cloves
tbls cumin
tbls smoked paprika
tbls oregano
2 tbls chilli powder
1 tsp salt
1 tin of beans, eg black eye, kidney, whatever (optional)
small jar/tin tomato puree (optional)
4 shots espresso
100ml ish of beef stock so it’s just wet
Brown mince + onions + garlic
Slow cooker for 3+ hours
Eat with lots of white rice, greek yoghurt and strong cheddar.
