To make the crema, blend mayo, sour cream, basil, cilantro, lime juice, olive oil, garlic salt, and white pepper until smooth. Chill until ready to use.
Heat olive oil in a skillet over medium-high. Add sausage slices and sear 3–4 minutes per side until browned. Remove and set aside.
Grill corn over direct heat or stovetop until charred (about 4 minutes per side). Once cooled, slice kernels off the cob.
In the same pan, sauté red onion for 2–3 minutes. Add bell peppers, carrot, tomato, and chopped scotch bonnet. Cook another 4–5 minutes until slightly charred but still vibrant.
Toss in zucchini, garlic salt, and black pepper. Let zucchini cook undisturbed for a minute to get color, then stir and cook 3 more minutes.
Return sausage and corn to skillet. Toss everything together and cook for 2–3 minutes. Remove from heat. Stir in chopped basil and cilantro.
Plate on its own or over rice. Drizzle with crema and top with extra herbs, if desired
Enjoy!
