This vibrant grilled steak and mixed peppers dish is a fantastic option for those seeking a nutritious, diabetes-friendly meal that does not compromise on smoky, char-grilled flavour. By using high-quality strip steaks and a colourful medley of mini sweet peppers and shishitos, you create a plate that is as visually appealing as it is satisfying. The natural sweetness of the peppers perfectly balances the rich, savoury notes of the beef, while a simple seasoning of sea salt and olive oil lets the fresh ingredients shine.
Perfect for a weekend lunch or a light midweek dinner, this recipe focuses on lean protein and fibre-rich vegetables. Slicing the steak against the grain ensures a tender texture, while the resting period allows the juices to redistribute for a succulent finish. Serve it as a standalone meal or with a crisp green salad for a wholesome, low-carbohydrate feast.

How to make Grilled Steak and Mixed Peppers
Back to contentsSeason steaks on all sides with 2 teaspoons kosher salt and 2 teaspoons pepper. Let sit at room temperature 1 hour.
Prepare a grill for medium-high heat; oil grate. Grill steaks until lightly charred and an instant-read thermometer inserted into the thickest part registers 49°C, 6–8 minutes per side for medium-rare. Transfer to a cutting board and let rest 10 minutes before slicing against the grain.
Meanwhile, grill sweet peppers, turning often, until lightly charred and softened, about 5 minutes. Transfer to a platter and cover with foil. Grill shishitos, turning often, until lightly charred and softened, about 3 minutes. Transfer to platter with sweet peppers and cover with foil. Let rest 10 minutes. Drizzle with 2 tablespoons oil, then season with 1/2 teaspoons kosher salt and 1/4 teaspoons pepper and toss to combine.
Transfer sliced steak to platter alongside peppers. Drizzle with oil, then season with sea salt and pepper.
