Prep the Ingredients: If using frozen edamame and corn, thaw them under running water. Drain and set aside. Dice the red bell pepper and chop the onion and garlic.
Sauté Aromatics: In a large skillet, heat the olive oil over medium heat. Add the diced red onion and sauté for about 3-4 minutes, until they start to soften.
Add Garlic and Bell Pepper: Stir in the minced garlic and diced red bell pepper. Cook for an additional 2-3 minutes until the bell pepper is tender.
Incorporate Edamame and Corn: Add the shelled edamame and sweet corn to the skillet. Stir to combine all the ingredients.
Season the Mixture: Sprinkle in smoked paprika, salt, and pepper. Mix thoroughly and cook for about 5-7 minutes, letting everything heat through and the flavors meld.
Finish with Lemon Juice: Once cooked, remove the skillet from heat and drizzle lemon juice over the succotash. Toss gently to combine.
Garnish and Serve: Transfer the succotash to a serving dish and sprinkle chopped cilantro on top as a garnish.
