Step 1

Make the aioli. Combine egg, chopped garlic, and fresh lemon juice in the bowl of a food processor fitted with blade attachment. Process until finely chopped, then with the motor running slowly stream in the canola oil. Continue to process for 30 seconds, or until well incorporated. Scrape down the sides then process once more.

Step 2

Finish the aioli. Transfer to a large mixing bowl, then stream in the extra virgin olive oil, whisking the entire time. The aioli will be smooth, thick, and pale yellow. Add finely chopped tarragon, Kosher salt, and black pepper. Stir to mix, then refrigerate until needed.

Step 3

Toast bread. 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!

Step 4

Assemble the California club sandwiches. Spread a thin layer of tarragon aioli on both sides of toasted bread. To the bottom piece, layer the following: 1 ½ strips crispy bacon, thinly sliced turkey, 2 slices tomato. On the top slice of bread, place a layer of thinly sliced avocado. Season both the tomato and avocado with a little Kosher salt and black pepper. Place a generous handful of arugula (or other greens) on top of tomato, then flip the bread with avocado on top.

Step 5

Secure with skewers. 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.

Step 6

Slice the sandwich. Use a sharp knife to cut the sandwich in an X shape, creating 4 triangular pieces. Pick each piece up and press the toothpick or skewer through the rest of the way. Serve immediately!
