Preheat Oven: Preheat your oven to 180°C (350°F).
Toast Pecans: Spread the pecans on a baking tray and bake in the preheated oven for 4 minutes. After 4 minutes, give them a toss, then bake for another 4 minutes. Be attentive and remove them from the oven when you start to smell the toasting aroma and before they become too browned. Set aside to cool, then chop into smaller pieces.
Prepare Ingredients: Chop the broccoli into small pieces, about 1 cm. Finely slice the red onion. Chop the dried cranberries. Chop or crumble the feta cheese.
Make Dressing: In a small bowl, combine the red wine vinegar, lemon juice, Dijon mustard, olive oil, and black pepper. Mix together until well combined, then add in 1 tablespoon water to thin it out.
Assemble Salad: In a large mixing bowl, add the chopped broccoli, sliced red onion, chopped cranberries, crumbled feta cheese, and toasted/chopped pecans. Mix together well.
Dress Salad: Pour the prepared dressing over the salad ingredients in the bowl. Toss all the ingredients together until the salad is evenly coated with the dressing.
