Best roast beef ever

I don't have a recipe or anything b/c DH made this and I'm pretty sure the recipe is in some secret food-network-type archive in his brain but I had to share a picture. I am NOT a big fan of Roast Beef. I'm thankful beyond words when someone makes us RB for dinner or we have extra stored in our freezer but this - slow roasted beef turned into a big chunky-meat chili and then served with tortilla chips...oh man....now we're talking. I didn't even have to get ketchup out for this roast beef meal :) The picture's not the greatest either - I didn't have time to mess around with presentation and all that - I was hungry!
