Preheat your oven to 450°F (230°C). Place the whole red and yellow bell peppers on a baking sheet lined with parchment paper or foil. Roast them in the oven for about 20-25 minutes, turning occasionally, until the skins are charred and blistered all over.
Remove the peppers from the oven and immediately transfer them to a bowl. Cover the bowl tightly with plastic wrap or a plate to let the peppers steam for about 10 minutes. This steaming process helps loosen the skins, making them easier to peel.
Once the peppers are cool enough to handle, peel off the charred skins. Remove the stems and seeds, then slice the peppers into strips or bite-sized pieces, depending on your preference.
Thinly slice the red onion and finely chop the fresh parsley. Crumble the feta cheese so it’s ready to sprinkle over the salad.
In a small bowl, whisk together the olive oil, fresh lemon juice, salt, and pepper. This simple dressing will enhance the natural flavors of the roasted peppers and feta without overpowering them.
In a large mixing bowl, combine the roasted pepper slices, red onion, and parsley. Pour the dressing over the salad and toss gently to combine. Finally, sprinkle the crumbled feta cheese on top. Give the salad one last gentle toss or leave the feta on top for a pretty presentation.
Serve immediately at room temperature or chilled for a refreshing twist. Enjoy this vibrant salad on its own or alongside your favorite dishes!
