I have made this salad many times. It is very nice without bacon. But if you insist on bacon don't ruin the recipe with bacos. 2-3 spring onion is nice and mild replacement for red onion. making both salad and dressing ahead of time helps blend the flavors. however, don't add the dressing till just before serving or salad can become too "wet". does not make a good left over salad. the amount of dressing called for in this recipe is enough to double up on the broccoli and grapes. sunflower seeds should be roasted and salted. i have also made with optional 1/4 teaspoon garlic salt added to dressing which is nice. white pepper to taste, but no need for additional salt.
Delicious! I omitted the raisins and used only a teaspoon of sugar since I like it a little less sweet. I can't wait to make it again. Thank you so much!
