Roast with Red Gravy

So I was trying to make something along the lines of barbecued beef. I had a rump roast so it didn't shred like I would have liked, but that's okay because the sauce wasn't quite up to barbecue standards although it was quite good. I ended up with far more sauce than we will use for the roast, but I'm thinking the remainder will be good on pasta if I throw in some Italian sausage and some basil and oregano. Some also liked the extra sauce over mashed potatoes although it was a bit weird for me.

Roast with Red Gravy

rump roast (or whatever cut you have)
1 28 oz can crushed tomatoes
2-3 carrots, diced
1-2 stalks celery, diced
1 onion diced
4 cloves garlic, minced
1/2 tsp. crushed red pepper (or one dried jalapeno, crushed-if you're lucky enough to have one)
1 bay leaf
1/2 tsp. chipolte powder, optional
1 tsp. dried thyme
1/2 cup brown sugar
1/2 cup cider vinegar
salt & pepper to taste

Mix everything but roast together in the crock pot. Add roast and cook on low for 8 hrs or so. When in roast is done,remove the bay leaf and puree the vegetables in the blender (probably best to do in two batches-careful, it's hot). Slice the roast and serve with sauce.
