Melt butter in a large sauté pan over medium-high heat. Add seasoned Tilapia, onions and garlic, and allow to brown.
Turn fish and add remaining ingredients. Cook for approximately three minutes, or until fish is done.
To serve, place the cooked vegetables on a plate with the fish on top. Add a handful of mixed greens to the plate and spoon the butter sauce on top.
