Ingredients

Canola oil cooking spray

3/4 pound 
small red potatoes, diced
1/2 pound
 green beans, trimmed
2 tablespoons olive oil
2 tablespoons
red wine vinegar
1 tablespoon water
1/8 teaspoon
 salt (optional)
1/2 
medium clove garlic, minced
1/8 teaspoon
 dried red pepper flakes
1 tablespoon chopped fresh oregano leaves
4 tuna steaks
4 cups (2 oz) 
baby spinach leaves
16 
pitted kalamata olives, chopped

Preparation

Steam potatoes and beans 6 minutes until just tender. Drain and rinse with cold water, shaking off excess liquid. Combine olive oil, vinegar, water, salt, garlic, red pepper flakes and oregano in small jar to make vinaigrette. Cover tightly and shake well to blend. Set aside 1/4 cup vinaigrette and brush the rest (1 tablespoon) over fish.

Coat a grill pan with cooking spray and heat over medium-high flame until hot. Grill tuna over high heat 3 minutes on each side or until medium-rare or to desired doneness. Divide spinach on four serving plates. Arrange potatoes, green beans, and olives over greens. Drizzle one tablespoon vinaigrette on each salad. Top with tuna and enjoy!
