I have no idea how I came up with this recipe. I have been making it ever since I graduated High School (1990). It is really yummy and quick/easy to fix. I just made it for the first time for my husband's family for a potluck. We didnt bring any home - it went over that well! This is by far my favorite casserole in the world. I hope you enjoy it as much as we do!
Heat oven to 350 degrees. Brown hamburger seasoned with garlic powder, worcestershire sauce, paprika, salt and pepper. When cooked through mix both cans of tomato paste in the hamburger mixture. Spoon into 9X13 pan and spread evenly.
Layer thawed and drained frozen mixed veggies on top of the hamburger layer.
Evenly spread prepard mashed potatoes on top. Bake uncovered, on middle rack until heated through. Enjoy!
