👩🏼🍳 Chef's Tips
- Chop Giardiniera Finely: Make sure to chop the Giardiniera into small, even pieces. This ensures a smooth consistency in the sauce and makes it easier to spread on sandwiches or mix into a creamy grinder salad.
- Taste as You Go: Always taste the sauce after mixing. The balance of tangy red wine vinegar, creamy mayonnaise, and bold Giardiniera is key. Adjust the seasoning with salt or black pepper to make it perfect for your palate.
- Let It Chill: If you have the time, refrigerate the sauce for at least 15 minutes before serving. This allows the flavors to meld together, creating a more cohesive and delicious tangy dressing.
📖 Substitutions & Variations
Giardiniera Substitute: If you don’t have Giardiniera, use a mix of finely chopped banana peppers, pepperoncini peppers, and your favorite pickled vegetables like red onion. These ingredients will replicate the zesty crunch and spice of the original.
Lighter Option: For a lower-fat version, swap the mayonnaise for Greek yogurt or light mayonnaise. This will maintain the creamy texture while reducing the calorie count.
Extra Heat: If you love a spicier kick, add a pinch of red pepper flakes or a splash of hot sauce to the sauce. This pairs perfectly with savory deli meats and crunchy lettuce on a hoagie roll.
Vegan Variation: Use vegan mayonnaise (olive oil based) and a plant-based Giardiniera to create a tangy, dairy-free dressing that’s just as flavorful and versatile.
