Preheat oven to 375 degrees
Spread the sloppy joe sauce on the bottom of a 9 by 13 baking dish.
Spread the mixed veggies on top.
Gently pour the water on the top.
Add the cheese to the top.
Top with tater tots.
Bake at 375 degrees for 45 minutes or until bubbling. Tip: to get the tater tots extra crispy and the cheese bubbling, turn the broiler on for the last 5 minutes, or so.
