Preparation
Preheat oven to 375°F (190°C) if baking, or prepare skillet for stovetop cooking.
Spread rinsed and drained beans on a paper towel-lined plate; pat thoroughly dry.
Mash half the beans in a large bowl, leaving the other half whole for texture.
Making the Mixture
Heat 1 tablespoon olive oil in a skillet over medium heat.
Sauté onion and bell pepper until softened, 5-7 minutes.
Add garlic, cook until fragrant, about 1 minute.
Combine sautéed vegetables with mashed and whole beans.
Add rice/quinoa, oats, soy sauce, lime juice, and all seasonings.
Mix gently until well combined, avoiding overmixing.
Forming and Cooking
Divide mixture into 4 equal portions (about 1/2 cup each).
Form into patties approximately 3/4 inch thick.
Choose your cooking method:
Stovetop: Cook in oiled skillet over medium heat, 5-7 minutes per side
Oven: Bake on parchment-lined sheet at 375°F for 15-20 minutes, flipping halfway
Grill: Cook on oiled grill grates over medium heat, 5-7 minutes per side
Pro Tips
Pat beans very dry to prevent mushy burgers
Chill formed patties for 30 minutes before cooking for better binding
Don't skip sautéing the vegetables - it removes excess moisture
Keep patties around 3/4 inch thick for optimal cooking
Press a small thumb indent in center of patties to prevent doming
Let cooked patties rest 5 minutes before serving
Troubleshooting
Too wet: Add more oats, 1 tablespoon at a time
Too dry: Add 1-2 tablespoons vegetable broth
Falling apart: Ensure beans are well-mashed and mixture is properly chilled
Not browning: Ensure pan/grill is properly preheated
Sticking: Use more oil or ensure cooking surface is well-greased
