1¼ lbs. kale (or spinach), stems removed
3 tbsp. olive oil
3 cloves garlic, minced
1 tsp. red pepper flakes
1 (28 oz.) can crushed tomatoes, (preferably with herbs)
2 tsp. kosher salt, divided

To prepare the kale, bring a large pot of salted water to boil. Add the kale to the pot and boil for 2 minutes. Drain and rinse with cold water until cool enough to handle. Wrap the kale inside a clean kitchen towel and wring out as much excess liquid as possible. Chop roughly, season with salt and pepper, and set aside.

To make the tomato sauce, combine the oil, garlic, red pepper flakes and 1 teaspoon of kosher salt in a cold saucepan. Heat over medium-high, stirring frequently. Once bubbling, cook for about 30 seconds. Mix in the crushed tomatoes, reduce heat and let simmer 5-10 minutes. Remove from the heat and stir in the lemon juice.

To make the cheese mixture, strain all of the liquid out of the cottage cheese. (I used a fine mesh strainer and pressed down to remove the liquid.) Mix in ½ cup of the Parmesan, 1½ cups of the mozzarella, 1 teaspoon salt and the pepper.

Preheat the oven to 375˚ F. To assemble the lasagna, add a thin layer of the sauce to the bottom of a 9 x 13-inch baking dish. Cover with a layer of noodles, then half of the cheese mixture, half of the kale, and half of the remaining sauce. Add another layer of noodles, the remaining cheese mixture, and the remaining kale. Top with the remaining noodles, then the remaining sauce. Sprinkle with the remaining ½ cup mozzarella cheese and ¼ cup Parmesan.
