Heat 2 tablespoons oil in a large skillet over medium-high heat. When oil shimmers, add shallots and saute until golden, 2 minutes.
Add edamame, corn, salt, and pepper and continue to cook, stirring occasionally, until vegetables are heated through and browned in places, about 5 minutes.
Remove from heat; stir in basil and remaining tablespoon oil and serve.
This is a great recipe, easily adjusted to a smaller family.
It does not retain it's flavor as a leftover, in my opinion, so I adjust.
