1. Broil poblano peppers 4 inches from the heat until skins blister, about 5 minutes. With tongs, rotate peppers a quarter turn. Broil and rotate until all sides are blistered and blackened. Immediately place Poblano peppers in a medium bowl; cover with bowl with plastic wrap and let stand for 20 minutes.
2. Peel off and discard charred skins. Remove the stems and seeds and coarsely chop the peppers.
3. In a Dutch oven, heat oil over medium-high heat, brown beef in batches. Remove beef and keep warm. Reduce heat to medium, in the same pan, saute the onion until tender. Add in the garlic and cook for 1 more minute.
4. Pour in broth; stir in the tomatoes, cilantro, Worcestershire Sauce, chili powder, salt, cumin, red pepper flakes, pepper, Poblanos and beef.
5. Bring the stew to a boil. Reduce heat; cover and simmer 1-1/2 hours or until beef is tender. Add potatoes; cook 20-30 minutes longer or until potatoes are tender. Skim fat.
Notes
- Instead of canned tomatoes, you can substitute 2 medium fresh tomatoes. Just chop them up and toss them into the pot- This stew is a little on the soupy side, but you could definitely thicken it up with a little corn starch and cold water. We chose to eat it as is.Adapted from Taste of Home
