I just used what I had around the house to flavor up my tilapia tonight! Start by squeezing the juice of two lemons over your tilapia (I used 2 pieces of fish). Add about 3 or 4 slabs of butter on top of the fish and season well with salt, pepper, and garlic powder. Slice up a handful of mushrooms and bell pepper. Mince about 2 stalks of green onion and throw those into pan. Bake in the oven at 375 degrees for 25 minutes. Put foil over the pan for the last 10 minutes to make sure the veggies get cooked.
