First of all, I have to say this had great flavor without adding any herbs, spices or in the Chef's words "some heat". I used a cheap cut of steak (round). The directions did not indicate how thick the strips should be, so I cut them about 1/4 in thick. I did thicken the sauce to make a gravy by taking some of the sauce out and adding a couple of tablespoons of flour to the removed sauce. Made sure it was mixed well and then slowly incorporated it back into the crockpot. I also added the optional sour cream at the end. To add color I would add some red bell pepper along with the green bell pepper that is called. I would also add some sliced onion-maybe about a 5 to 6 ounce onion sliced. Finally, my husband said he would have liked to have some more peppers that had a little crisp to them. Probably about an hour or so before the dish is done, I would add one more green and red bell pepper that had been sliced into strips. Overall this was a great dish and I will add it to our menu.
