Ingredients
  

  • 2 cans whole green beans (drained)
  • 1 red onion (small, sliced)
  • 10 mushrooms (medium, sliced)
  • 2 tbsp oil
  • 3 tbsp vinegar
  • ¼ tsp salt
  • ¼ tsp oregano
  • ¼ tsp thyme
  • ⅛ tsp black pepper

Instructions
 

Step 1: Prepare Vegetables

  • Drain the canned green beans thoroughly.
  • Slice the red onion and mushrooms into thin, even pieces.

Step 2: Make Dressing

  • In a small bowl, whisk together oil, vinegar, salt, oregano, thyme, and black pepper until well combined.

Step 3: Combine Salad

  • In a large mixing bowl, add the drained green beans, sliced mushrooms, and red onion.
  • Pour the dressing over the vegetables and toss gently until fully coated.

Step 4: Chill & Serve

  • Cover the bowl tightly and refrigerate for at least 3 hours to allow flavors to blend.
  • Serve cold.

Tips

  • Use fresh or frozen green beans instead of canned; briefly blanch, then chill before dressing.
  • Substitute white wine vinegar or apple cider vinegar for a slightly sweeter flavor.
  • Add cherry tomatoes or sliced bell peppers for color and crunch.
  • Let the salad marinate overnight for deeper flavor.
  • Sprinkle with feta or parmesan if dairy is acceptable (omit to keep vegan).
  • Swap red onion for sweet onion if you prefer a milder taste.
  • Add crushed red pepper flakes for gentle heat.
  • Use extra-virgin olive oil for a richer vinaigrette.
  • Garnish with fresh herbs (parsley, basil, or extra thyme) right before serving.
