Heat the olive oil in a large skillet over medium heat.
Add the diced yellow onion, poblano pepper, red bell pepper, and minced garlic. Sauté until the vegetables are translucent, about 5-7 minutes.
Stir in the corn kernels, salt, and pepper. Cook until the corn turns a vibrant yellow, about 3-5 minutes.
Add the butter to the skillet and stir until melted and well combined.
Add the shelled edamame and cherry tomatoes. Mix well and cook for an additional 2 minutes until everything is heated through.
Serve the succotash right away while it’s warm.
Notes
Prep Work is Key - Ensure all your ingredients are prepped and ready to go before you start cooking. This includes dicing the vegetables, shelling the edamame, and halving the cherry tomatoes. Having everything ready will make the cooking process smooth and efficient. Make sure you have a sharp knife for prep! Don't Overcook the Corn - Corn kernels can quickly become mushy if overcooked. Cook them just until they turn a vibrant yellow, retaining a slight crunch for added texture.Butter for Richness - Adding butter at the end of cooking lends richness and a silky texture to the succotash. Stir it in gently until fully melted and incorporated for the best flavor.
