Prepare the Mixture
Combine the lentils, black beans, onions, garlic, breadcrumbs, oat flour, mushrooms, parsley, Worcestershire sauce, salt, and pepper in a food processor. Blend until smooth, leaving it slightly grainy if you prefer more texture.
Tip: If the mixture is too wet, add more breadcrumbs or oat flour to reach the desired consistency.
Form the Patties
Divide the mixture into 16 portions and form them into small burger patties. Place the patties on parchment paper.
Tip: Wet your hands slightly to prevent the mixture from sticking while forming the patties.

Cook the Patties
Grease a non-stick skillet and bring it to medium-high heat. Add the burgers and cook them on both sides until they are golden brown, about 8-10 minutes per side.
Tip: Avoid overcrowding the skillet; cook the patties in batches if necessary to ensure even cooking.
Serve the sliders in small burger buns with fresh cucumber, red onion, and your favorite sauce. For added flavor, toast the buns lightly before assembling the sliders.

Notes
- Consistency: The mixture should be firm enough to hold together. If it’s too wet, add more breadcrumbs or oat flour. If it’s too dry, add a little water or vegetable broth.
- Mushrooms: Finely chop the mushrooms for a better texture. They add a meaty flavor and help bind the patties.
- Lentils and Beans: Make sure the lentils and black beans are well-drained to prevent excess moisture in the patties.
- Herbs and Spices: Feel free to add your favorite herbs and spices to the mix. Cumin, smoked paprika, or thyme can add a nice depth of flavor.
- Blending: When blending the mixture, pulse it instead of running the food processor continuously. This helps maintain some texture and prevents it from becoming too smooth.
- Forming Patties: Wet your hands slightly when forming the patties to prevent sticking and to make shaping easier.
- Cooking: Use a non-stick skillet and don’t overcrowd it. Cook the patties in batches to ensure even cooking and a nice golden-brown crust.
- Serving: Toast the buns lightly before serving for extra flavor and texture. Top the sliders with fresh vegetables like cucumber and red onion, and add your favorite sauce to enhance the taste.
- Freezing: These patties freeze well. Make a big batch, freeze them on a baking sheet, then transfer to a freezer bag. They’re perfect for a quick meal later.

How to Store Veggie Sliders
To keep your leftover veggie burger sliders fresh and tasty, store them properly. Once cooked, let the patties cool completely. Place them in an airtight container, separating each patty with parchment paper to prevent sticking. They will keep well in the refrigerator for up to 4 days.
