Slowcookertrackworld. Lets have your recipes then?

Help Required……

I have 1lb of diced beef
2 peppers
red onion
mange tout
garlic
various herbs
celery
Oxo cubes
Tin of chopped tomatoes

Now what exactly should I do with that lot?

Lose the mange tout, don’t bother with the chopped tomatoes, put the rest in the slow cooker, pour over the beer of your choice, and Robert’s your aunties live-in lover

Could anyone please suggest a solution to this problem?
I’m getting much the same outcomes as Marko above. Smells great, looks fine but taste and texture in the mouth is always a bit meally and dry, not especially pleasant. Any clues what has been going wrong? Cooker is usually on for about 8 hours, with say, beef, beer & veg recipes.
