First steam your veggies until very tender. The veggies need to be soft enough so make sure you steam until they fall apart with the touch of a fork.
Next drain any water and place veggies in a large mixing bowl.
Using a fork, mash/mix around the veggies a little until they are smaller pieces. You can use a food processor and pulse if you want…but a fork works just fine and it saves on time so you don’t have to wash more dishes!
Add minced garlic, butter, sour cream, greek yogurt, salt, pepper, half and half. Stir well then mix in sharp shredded cheese.
Place in a 8x10 baking dish and bake 350 for about 30-45 minutes or until golden brown and bubbly.
