Gather and prep all ingredients.

In a bowl, put together mayonnaise, water, garlic powder, and salt and pepper to make the dressing. Stir until combined well and set aside.

Boil the eggs for about 8-10 minutes. When cooled, peel and slice in half.

Wash and cut the asparagus into equal lengths. Fry the asparagus in a pan by itself.

Equally pour the olive oil on both sides of the fresh tuna and fry for 3-5 minutes on both sides. Season the tuna with salt and pepper, to taste.

On a plate, place the leafy greens, cherry tomatoes (cut in half), onion, and eggs.

Cut the grilled tuna into slices and place on top. Pour the dressing on top of the salad and sprinkle the chopped walnuts on top of that.
