Equipment

• Large mixing bowl
• Fork or potato masher
• Grater (for the carrot)
• Knife & chopping board
• Measuring cups & spoons
• Non-stick skillet or frying pan
• Spatula
• Baking sheet & parchment paper (for oven method)

Instructions

1. Prepare the patty mixture:

   In a large mixing bowl, add the drained black beans. Use a fork or potato masher to mash about 3/4 of the beans, leaving some whole for texture.

2. Mix in the veggies:

   Add the grated carrot, diced red onion, and minced garlic to the bowl. Stir well to combine.

3. Add the grains & seasonings:

   Stir in the cooked quinoa, breadcrumbs, smoked paprika, cumin, chili powder (if using), salt, and pepper.

4. Bind the mixture:

   Add the egg (or flax egg: 1 tbsp ground flaxseed mixed with 2.5 tbsp water, set for 5 min). Use your hands or a spatula to thoroughly combine until the mixture holds together when pressed.

   “If your mixture feels too wet, add more breadcrumbs. Too dry? Add a splash of water or a little olive oil.”

5. Shape the patties:

   With damp hands, form the mixture into 8-10 small patties, each about 2 inches in diameter and 1/2 inch thick. Place on a plate or parchment-lined tray.

6. Cook the patties (Stovetop Method):

   Heat 1-2 tbsp olive oil in a non-stick skillet over medium heat. Once hot, add patties in a single layer.

   Cook for 3-4 minutes on each side until golden and heated through.

7. Cook the patties (Oven Method):

   Preheat the oven to 400°F (200°C). Place patties on a parchment-lined baking sheet.

   Brush lightly with olive oil and bake for 15-18 minutes, flipping halfway, until crispy.

8. Toast the slider buns:

   Slice buns in half and optionally toast them in a dry skillet or oven for 2-3 minutes for extra flavor and texture.

9. Assemble the sliders:

   Place a patty on the bottom half of each bun. Top with lettuce, tomato slices, pickles, cheese (if using), and your favorite sauces.

   Cap with the top bun.

   “Try a homemade sauce like spicy mayo, chipotle aioli, or classic ketchup and mustard for an extra kick!”

10. Serve & enjoy:

    Serve your sliders warm with a side of fries, salad, or crunchy veggie sticks.

Tips & Variations

• Make it vegan: Use a flax or chia egg instead of regular egg, and opt for dairy-free cheese.
• Swap the beans: Try kidney beans, chickpeas, or lentils for a different flavor and texture profile.
• Spice it up: Add chopped jalapeños, hot sauce, or cayenne for extra heat.
• Change up the grains: Brown rice, farro, or even cooked bulgur work well in place of quinoa.
• Cheesy surprise: Stuff each patty with a small cube of cheese before cooking for a melty center.
• Make ahead: Form uncooked patties and refrigerate (up to 2 days) or freeze (up to 2 months). Cook straight from the fridge or thawed from the freezer.
• Gluten-free: Use gluten-free breadcrumbs and buns.
• Batch cooking: Double or triple the recipe for parties—these go fast!
