To make the old-school red wine vinaigrette: Combine vinegar, lemon zest and juice, Dijon, salt, pepper, and shallot in a blender. Blend until smooth, about 2 minutes on high speed. Combine both oils in a cup or a small bowl, then stream into blender while running on low speed. Stir in oregano and store in an airtight container in fridge for up to a month.

To make the lime-pickled onions: Use a Chef Knife to cut off top of onion but leave root intact. Slice lengthwise down middle and lay both halves flat on cutting board. Remove root and slice thinly down one onion half, slicing lengthwise with grain. Do same for other half of onion. Place onion in a medium bowl, then add salt and sumac and rub them with your hands. Add lime juice and cover for at least an hour. Onion slices will turn a beautiful pink color the longer they pickle. Store in an airtight container in fridge for up to 3 weeks.

To toast the bread: Heat an Enameled Cast Iron Skillet or large Carbon Steel Frying Pan over medium, or prepare a grill for medium heat. Brush both sides of bread with olive oil and season with salt and pepper. Toast in the Skillet or grill until there is a beautiful char on both sides, 2–3 minutes per side, then use a Bread Knife to cut into bite-size pieces.

To prep the fennel: Use a Chef Knife to remove the stalks, reserving some of the fronds for serving. Cut bulbs lengthwise, through root. Remove root end and slice thinly from top to bottom using either a knife or a mandoline. If prepping in advance, hold the sliced fennel in a bowl of ice water.

To make the salad: Combine fennel, arugula, ½ cup of lime-pickled onions, and pomegranate arils in a Serving Bowl. Season with salt and pepper. Add ½ cup of old-school red wine vinaigrette and toss well. Add cubed bread, basil, and reserved fennel fronds and toss to combine. Add another 2 Tbsp. of vinaigrette and make sure it is well dressed. Divide among bowls and finish with grated Parmigiano-Reggiano and a dusting of sumac.
