In a small bowl, mix together salt, garlic powder, pepper, cumin, brown sugar and basil.
Rinse tuna and pat dry. Rub with spice mixture.
Heat oil in a 12-inch skillet over high heat. Add the tuna, being careful not to crowd.
Sauté 2 minutes on each side, until seared. Tuna should be cooked outside and still red inside. Set aside.
Place beans in a large bowl. Add oil, lemon juice, pepper, garlic powder and parsley. Stir gently to mix.
To serve, divide bean mixture among 6 plates and top each with a tuna steak.
