1 1/2 pounds ground beef, lamb, or other protein of your choice
2 1/2 cups chopped vegetables. I used Bird's Eye Ultimate Petite Mixed Vegetables, which is a mix of peas, corn, green beans, and carrots. Other good options are celery, mushrooms, parsnips, and pearl onions. I also added a can of mushroom stems & pieces.
6 russet potatoes
8 tbsp butter (1 stick)
1/2 cup beef broth (substitute vegetable broth if vegetarian)
1 tbsp. Worcestershire sauce
Salt & pepper to taste
