Ingredients
To make this flavorful dish, you’ll need:

- 2 large onions, sliced (about 400 g / 0.9 lb)
- 3 tablespoons olive oil (45 ml)
- 1 teaspoon salt (5 g)
- ½ teaspoon black pepper (2 g)
- 1 teaspoon garlic powder (3 g)
- 1 teaspoon paprika (3 g)
- ½ teaspoon dried oregano (1 g)
- Optional: 1 tablespoon lemon juice (15 ml) for added brightness
Step-by-Step Instructions
1. Prepare the Vegetables
Wash the bell peppers thoroughly, remove the seeds, and slice them into even strips. Peel the onions and cut them into thick slices to prevent them from falling apart during grilling.
2. Season the Vegetables
In a large bowl, combine the sliced peppers and onions. Drizzle with olive oil and sprinkle salt, black pepper, garlic powder, paprika, and oregano. Toss everything well until evenly coated.
3. Preheat the Grill
Heat your grill to medium-high (around 200°C / 400°F). If using a grill pan, preheat it over medium heat.
4. Grill the Vegetables
Place the vegetables directly on the grill or use a grill basket. Cook for 10–15 minutes, turning occasionally, until they are tender and slightly charred.
5. Finish and Serve
Remove from the grill and drizzle with lemon juice if desired. Serve warm as a side dish or topping.

Frequently Asked Questions
1. Can I make this recipe without a grill?
Absolutely. If you don’t have access to an outdoor grill, you can easily prepare this dish using a stovetop grill pan or even a regular skillet. A grill pan will give you those beautiful char marks and smoky flavor, while a skillet will still allow the vegetables to caramelize nicely. Roast them in the oven at 220°C (425°F) for about 20–25 minutes if you prefer a hands-off method.
2. Which bell pepper colors work best?
You can use any combination of red, yellow, green, or orange bell peppers. Red and yellow peppers tend to be sweeter, while green peppers have a slightly more bitter, earthy flavor. Mixing colors not only enhances taste but also creates a visually appealing dish that’s perfect for serving guests.
3. How do I store leftovers?
Store leftover grilled bell peppers and onions in an airtight container in the refrigerator for up to 4 days. To reheat, simply warm them in a skillet over medium heat or microwave them for 1–2 minutes. You can also enjoy them cold in salads or sandwiches.
4. Can I prepare this dish in advance?
Yes, you can slice and season the vegetables ahead of time and store them in the refrigerator for up to 24 hours before grilling. This can actually enhance the flavor as the spices have more time to infuse. However, for the best texture, it’s recommended to grill them fresh just before serving.
