Easy Shepard's Pie

My fiance loves the Shepard's Pie at Foran's Irish Pub in downtown Detroit. Although this isn't as great as theirs, it is a great recipe to hold him over in-between trips!

1 17 oz. package refrigerated cooked beef tips with gravy
2 cups frozen mixed vegetables
1 11 oz. can condensed tomato bisque soup
1/4 cup finely chopped onion
1 tablespoon Worcestershire sauce
1/2 teaspoon dried thyme, crushed
1/8 teaspoon ground black pepper
1 24 oz. package refrigerated mashed potatoes
1/2 cup shredded cheddar cheese

Preheat oven to 375. Lightly spray a 2-qt. baking dish with cooking spray, set aside. In a large saucepan, stir together beef tips with gravy, vegetables, onion, soup, thyme and pepper. Bring to a boil over medium heat, stirring occasionally. Transfer to baking dish.

Place potatoes in a large bowl, stir until smooth. Spoon potatoes into 6 mounds on top of beef mixture.

Bake uncovered in the preheated oven for 20-25 mins. or until heated through and bubbly around the edges. Sprinkle potatoes with cheese. Let stand for 10 minutes before serving.
