Spicy Shepherd's Pie

I got this recipe out of Taste of Home's "Weeknight Cooking Made Easy." This was SO tasty that we devoured all of the leftovers really quickly. I am posting the original recipe, but I do it a LITTLE differently. I use Rotel instead of diced tomatoes, and I didn't put in the olives. Enjoy!

• 1 (6 5/8ounce) package instant mashed potatoes
• 1  lb ground beef
