I make a wicked good beef, mushroom and barley soup:

lean stewing beef (1/2" cubes) marinated in a mix of beer, fruit based tenderizer,  sweet paprika and chopped celery leaf.

Portobella, tan-field and oyster mushrooms - diced

Onion, celery, carrots and garlic - chopped

rolled barley (rather than "pearled")

fat free, low salt beef stock (usually homemade)

a few lightly cracked peppercorns

Portobello and Beef Patty Melt Recipe

Ingredients
12 ounce(s) beef, lean ground, 93 % lean
2 cup(s) mushrooms, portobello, finely chopped, gills removed
3 tablespoon bread crumbs, fine, dry
1 tablespoon Worcestershire sauce
1 teaspoon thyme, fresh, chopped, or 1/2 teaspoon dried
1/4 teaspoon salt
1/4 teaspoon pepper, black ground
4 slice(s) bread, rye
1 clove(s) garlic, peeled
1/4 teaspoon 1% milk
8 teaspoon relish, sweet pickle
4 slice(s) cheese, Swiss, 2 ounces
Preparation
1. Position rack in upper third of oven; preheat broiler. Line a broiler pan with foil.

2. Gently mix beef, mushrooms, breadcrumbs, Worcestershire, thyme, salt and pepper in a medium bowl until combined. Shape into 4 patties and place on the prepared pan. Broil until cooked though, 4 to 6 minutes per side.
 
3. Meanwhile, toast bread. Rub each slice of toast with garlic.
 
4. Place 1 patty on each piece of toast, top each with 2 teaspoons relish and cover with a slice of cheese. Remove foil and place the sandwiches on the pan; broil until the cheese is just melted, 30 to 60 seconds.
