Flavor Base: Set the largest pan or pot you have over medium heat. Add oil (or butter), onion, garlic, and jalapeno. Cook until soft and fragrant, about 5 minutes.
Veggies: Increase heat to medium/high. Add corn kernels, zucchini, and bell pepper. Cover and cook, stirring occasionally, until zucchini is soft and corn is a bit brown around the edges, about 15 minutes.
Beans: Stir in the lima beans and cook until warm, about 3 minutes.
Serve: Remove from heat, and stir in remaining butter, basil, salt, pepper, and paprika. Serve warm.
