egg, garlic, lemon juice, canola oil, extra virgin olive oil, tarragon, kosher salt, black pepper
Here's What You'll Need (California Club)
sandwich bread, bacon, deli turkey, tomato, avocado, baby arugula, kosher salt, black pepper
Combine egg, garlic, and lemon juice in a food processor. Process until finely chopped, then slowly stream in the canola oil until well incorporated.
Transfer to a bowl, then stream in the olive oil, whisking the entire time. Add finely chopped tarragon, salt, and black pepper. Stir to mix, then refrigerate.
Once bread is toasted, either leave in toaster oven or place on a wire rack until all remaining ingredients are ready. This will help keep the bread crispy!
Spread aioli on bread. On bottom piece layer bacon, turkey, 2 slices of tomato. On top slice, place sliced avocado. Season with salt and pepper. Place a handful of arugula on top of tomato, then flip the bread with avocado on top.
Place 4 toothpicks or skewers into the sandwich in the shape of a compass (N, S, E, W). It's okay that they're not going all the way through the bread yet.
Use a knife to cut the sandwich in an X shape, creating 4 triangular pieces. Pick each piece up and press the toothpick or skewer through. Serve immediately!
