• Heat 2 tbsp olive oil in skillet set over medium heat; sauté onion for 3 minutes or until tender. Reduce heat to medium-low; stir in lima beans and corn. Sauté for 1 minute or until tender-crisp; transfer to large bowl. Let cool.
• Meanwhile, in small bowl, whisk together remaining olive oil, lemon juice, garlic, salt, mustard and pepper. Pour over corn mixture. Stir in tomatoes. Sprinkle with feta and basil.

Tip: If you can’t find lima beans, substitute steamed edamame or fava beans.
