Instructions:
- Cook the bacon in a skillet over medium heat until very crisp. Remove, drain excess fat, and crumble once cool. Set aside.
- Ensure the broccoli and cauliflower florets are very dry after washing. Dice the red onion finely.
- If using untoasted seeds, lightly toast them in the dry skillet used for the bacon over medium-low heat until fragrant (about 3-4 minutes).
- In a separate bowl, whisk together the mayonnaise, apple cider vinegar, sugar, Dijon mustard, celery seed, pepper, and salt until smooth and homogenous. Taste and adjust seasoning.
- In the large mixing bowl, combine the prepared broccoli, cauliflower, diced red onion, and toasted sunflower seeds.
- Pour about 2/3 of the dressing over the vegetable mixture. Gently fold everything together until the vegetables are evenly coated.
- Gently fold in the crumbled bacon and cubed cheddar cheese.
- Cover the bowl and refrigerate for at least 30 minutes to allow the flavours to meld and the vegetables to slightly tenderize.
- Toss lightly once more before serving. Add any remaining dressing if the salad looks too dry.
