Preheat oven to 375 degrees F
Head oil over large cast-iron skillet over medium heat
Add zucchini, onion and garlic and cook for about 5 minutes, stirring occasionally
Add in the ground meat and spices and cook everything together so the meat is no longer pink (I use a meat masher!)
Stir in tomato paste and broth and mix all together
Cook over medium low heat until broth has reduced, stirring occasionally
Remove skillet from heat and add cheese across then bake in oven for about 10 minutes. I like to broil for 1-2 minutes so the cheese bubbles a bit
Serve with desired toppings and fixings while warm!
