Place parsley, garlic, olive oil, vinegar, salt, and pepper into a blender. Pulse until smooth. Set aside in the fridge for at least one hour, but best if overnight. Mix with remaining ingredients.
Place the cabbage and onion in a large bowl, set aside. In a small bowl, whisk together the remaining ingredients, toss with the cabbage until coated. Set aside in the fridge for at least one hour, up to overnight.
Place lentils in a small stock pot, cover with cold water two inches above lentils. Bring to a boil, reduce to a simmer and simmer 10 minutes. Drain well and let cool to the touch.
While lentils are cooking, saute the onion, garlic and bell pepper with the olive oil until translucent over medium-low heat. About 5 minutes, set aside.
Add the lentils to a large bowl, add in the onion mixture, and remaining ingredients except for the cooking spray. Mix well.
Preheat broil on highest heat. Form patties from the lentil mixture in 1/4 cup measurements. Place patties on a foil-lined sheet tray that has been sprayed with cooking spray. Spray the tops of the patties as well.
Broil 5 minutes each side, until slightly golden brown. Top slider buns with yogurt sauce, lentil burgers, and dijon slaw.
The chimichurri yogurt sauce and dijon slaw have to be made at least one hour in advance.
