Mashed Potato or Potato Chip-Topped Mushroom and Tuna Casserole

Directions

1. Preheat the oven to 375. If you are topping the dish with mashed potatoes, follow the next few steps. If not, skip and crush the potato chips. Boil a pot of water for the potatoes. Peel, wash and cut them. Add the potatoes to the boiling water with a pinch of salt. (Be sure that the water covers them.) Boil until soft, drain and mash with the butter, salt/pepper and milk. Set aside.
2. In a skillet, add the oil over low/medium heat. Add the onion and cook until softened, 6 to 8 minutes then add the garlic and mushrooms. After the mushrooms softened, add the thyme or rosemary leaves. Cook for a few minutes until fragrant and stir in the olives (optional), seasoning, hot sauce (optional), salt/pepper and heavy cream. Stir for a few minutes, and then stir in the tuna. Remove from the heat, place in a casserole dish and either top with the mashed potatoes or place the cheese over the tuna mix and top with the potato chips. If using the mashed style, place the cheese on the top of them. Bake for 15 to 20 minutes, until golden brown.
