Avocado and Marinated Kale Salad Sandwich

Allow kale and shallots to marinate in lemon juice, then toss them together with sliced
radishes, Parmesan, and olive oil. Smear the bread with lemon-basil aioli and an avocado, and pile the salad between the two slices. 

Makes 3 to 4 sandwiches

For the avocado and kale sandwiches:

• 1bunch of lacinato kale, stemmed and shredded or very finely chopped
• 1small shallot, peeled and sliced very thinly (about 1 tablespoon)
• 1 1/2tablespoons fresh lemon juice
• 3smallish radishes, thinly sliced
• 1/4cup good aged Parmesan or Grana Padano, crumbled or shredded
• 3tablespoons olive oil
• Salt and pepper to taste
• 2ripe avocados
• Lemon-basil aioli (see below)
• 3 or 4ciabatta-ish rolls, sliced in half and toasted

1. Toss the shredded kale with 1 tablespoon of the lemon juice and a pinch of salt. Squeeze everything together with your hands several times to start to gently soften the kale's toughness. Set aside.
2. Meanwhile, toss the sliced shallot with the remaining lemon juice and set aside. Let both the kale and the shallot marinate for at least 30 minutes. Then, toss them together along with the sliced radishes, cheese, olive oil, and salt and pepper to taste.
3. For each sandwich, spread a toasted roll generously with lemon-basil aioli on one half. Smash half of an avocado on the other half and sprinkle with a pinch of salt. Pile on some kale salad, close the sandwich and eat. Simple!

For the lemon-basil aioli:

• 2tablespoons fresh lemon juice
• 1teaspoon lemon zest
• 1large egg yolk
• 1small garlic clove, chopped to a paste
• 1/2cup (approximately) neutral-flavored oil
• 3 to 4large basil leaves, finely chopped
• Salt and pepper, to taste

1. Whisk together the lemon juice, zest, egg yolk, and garlic. Whisk in the oil very slowly; start with one drop at a time and work up to a thin, steady stream as the mixture starts to thicken and emulsify. You can also whip everything together in a blender or food processor, but aioli made by hand has a better texture (and makes you feel more like a superstar). When enough oil is incorporated to reach your desired thickness, you can stop adding it and fold in the basil and salt and pepper to taste. Refrigerate for at least an hour before using to allow the flavors to settle and develop. (you can also just stir the lemon juice, zest, garlic, and basil into about 2/3 cup of store bought mayo and it'll still be really good).
