1 bag of arugula
1 or 2 red onions
2 large (4 baby) portobello mushrooms
12-16 ounces fish or steak (no bones)
Salt & pepper
Thinly slice the onion and mushrooms. Head some olive oil in a hot skillet and throw in the onions and begin the caramelization process... stirring every so often. Continue to cook the onion until about halfway caramelized. Add a splash of balsamic vinegar (the sweetness of the balsamic aids in the flavor and the caramelization process). Once almost finished, add the mushrooms and continue to cook together until nice and sweet.
Meanwhile, spread the arugula on a serving platter and sprinkle top with salt and pepper. Shave parmesan (lots!) on top and set aside.
While the onions are still cooking sprinkle both sides of the tuna/steak/whatever with salt, pepper, worcestershire sauce, and a bit of balsamic. Heat a grill pan (or an actual grill) to medium/medium high and sear the steaks. Cook to your liking. Remove from grill and slice.
Sprinkle the salad with olive oil and balsamic vinegar. Place the caramelized veggies on the platter and add the sliced tuna in the middle. Have guests serve themselves taking a bit of everything. Mmmm.
