Mini Shepherd's Pie Muffins

My stepdaughter thinks she hates vegetables so I make my mashed "potatoes" with a bag of frozen cauliflower steamed in the microwave, then pureed in the blender & then I add a small bag of flavored potato flakes to give it the right flavor and thickness. She eats it every time! I might have to puree the veggies into the ground beef for this recipe... We'll see!
