review_highlights:
  - theme: Flavor
    text: Many loved the taste, though some found it needed more seasoning. Adding Dijon mustard or extra spices boosted flavor.
  - theme: Ease of prep
    text: Patties can be tricky to cook through and may stick to the pan. Try air frying for crispy results.

Preheat oven to 425°F. Wash and dry produce. @potatoes{16%oz}(cut into ½-inch wedges). @sliced dill pickle{6%oz}(finely chop 2%tbsp for sauce, reserve remaining slices). @kidney beans{15%oz}(drain and rinse). @scallions{4%pieces}(trim and mince).

Toss potatoes on a #baking sheet{} with a drizzle of @cooking oil{3%tbsp}, @salt{1%tsp}, and @black pepper{1%tsp}. Roast on the top rack until golden brown and crispy ~{25%minutes}.

While potatoes roast, combine @mayonnaise{3%tbsp}, chopped pickles, @sugar{½%tsp}, and @hot sauce{1%tsp} in a #small bowl{} to make the secret sauce. Set aside.

Place half the beans in a #large bowl{} and mash until mostly smooth. Stir in @monterey jack cheese{2%oz}, scallions, @garlic powder{1%tsp}, @cajun spice blend{1%tbsp}, three-quarters of the @tempura batter mix{0.75%cup}, and 3%tbsp water until combined. Season with salt and pepper. Divide mixture into two mounds.

Heat a drizzle of oil in a #large pan{} over medium-high heat. Press bean mounds into patties the width of the buns. Cook until golden brown and crisp ~{4%minutes} per side. Transfer to a plate. (Work in batches if needed, adding more oil between batches).

Halve and toast @brioche buns{2%pieces} until golden. Spread cut sides with @butter{2%tbsp}. Spread bottom buns with half the secret sauce. Fill with bean patties and reserved pickle slices. Divide sandwiches between plates and serve with roasted potatoes and remaining sauce on the side.
