A casserole of meat, potatoes, and vegetables with southwest seasoning.

Servings

1 large onion , 8 oz (chopped)
2 medium garlic cloves , minced
3 oz shredded carrots , 1 carrot
0.5 lb button mushrooms , cleaned and sliced
1 lb Beef, sirloin, ground, extra lean, raw
1 tsp ground oregano
0.5 tsp ground thyme
0.5 tsp ground cumin
0.25 tsp black pepper
1 tbsp Flour, all purpose, unbleached, enriched
1 cup fat free unsalted beef broth , canned
0.33 cup red wine , dry (or additional beef broth)
2 tbsp tomato paste
1 cooking spray

Toppings
1 lb russet potatoes , peeled and cut into chunks
3 tbsp fat free milk
0.5 tsp salt (optional)
0.5 oz whole pickled jalapeno peppers , minced (1-2 tbsp)
1 tbsp fresh cilantro , minced (or flat-leaf parsley)
1 tbsp chopped scallions , minced
0.25 tsp paprika
3 tbsp Cheese, monterey jack, shredded , 2%

1 In a large nonstick skillet, sauté onion, garlic, carrot, and mushrooms over medium heat, stirring occasionally, until vegetables are wilted and pan liquids are absorbed, about 6 minutes.
2 Crumble in the ground sirloin and continue to cook, stirring occasionally, until beef is well browned, about 5 minutes. Drain off any excess fat.
3 Add oregano, thyme, cumin, and pepper. Sprinkle flour over the beef mixture and stir. Add beef broth, wine, and tomato paste. Stir until well combined.
4 Line a 2-quart casserole with a piece of heavy-duty aluminum foil large enough to completely enclose the casserole. Lightly spray the foil inside the casserole with cooking spray.
5 Transfer meat mixture to the prepared casserole. Set aside while you prepare the topping.
6 Place the potatoes in a pot of boiling water to cover. Reduce heat and simmer until tender when pierced with a fork, 15 to 20 minutes. Drain.
7 Mash the potatoes, adding sufficient skim milk until the potatoes are fluffy. Stir in the salt (if using), minced jalapeño chiles, cilantro, and scallion. Spoon the potato mixture onto the top of the meat mixture, making swirls with the back of a spoon. Sprinkle with paprika and cheese.
8 Bake at 375 degrees F for 40 to 45 minutes, until golden and bubbly (since the casserole will be full, it may bubble over, so place a sheet of aluminum foil under the casserole to catch any drips). Serve hot.

Consider using shredded pepper jack cheese for a little added "kick."
