Gather These Ingredients

This salad is built on simple, mostly pantry-friendly ingredients. You’ll grab fresh cauliflower, a few jarred vegetables, and a handful of pantry staples to whisk into a quick, tangy dressing.

• Fresh cauliflower: Raw florets work beautifully here, they soften slightly as they marinate while keeping that satisfying crunch.
• Jarred roasted red peppers and banana pepper rings: These bring sweetness and tang without any prep work, and they’re already drained and ready to go.
• Kalamata olives: Their briny, salty flavor is essential to the whole dish, don’t skip them.
• Red wine vinegar and Dijon mustard: Together, they create that punchy, tangy backbone that makes this salad sing.

How I Make Tangy Marinated Cauliflower Salad

The whole process is straightforward: make the dressing, toss everything together, and let time do the work.

Step 1: Whisk the dressing

In your serving bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, garlic powder, Italian seasoning, salt, pepper, and parmesan cheese. Taste it and adjust the seasonings until it’s bright, tangy, and delicious on its own.

Step 2: Add the vegetables

Add the chopped cauliflower florets, roasted red peppers, banana pepper rings, sliced olives, diced red onion, and fresh parsley to the bowl. Toss everything together until all the vegetables are well coated with the dressing.

Step 3: Chill and marinate

Cover the bowl and refrigerate for at least 30 minutes. Honestly, if you can make this the night before, do it, the flavors deepen and the florets soak up even more of that delicious dressing.

Step 4: Stir and serve

Give it a good stir before serving to redistribute the dressing. The salad will keep its texture and flavor for several days in the fridge.
