Plant-based sweet potato and kale patties bound with seeds and basil pesto, pan-fried until golden and served on toasted rolls with tomato pesto mayonnaise. The burgers are chilled before cooking to help them hold their shape, creating a crispy exterior while keeping the interior tender and moist.

Tips
Do not over-process the sweet potato mash; keep it lumpy for better texture.
Chilling the formed burgers is essential to help them hold their shape during cooking.
Toast the rolls lightly to add texture and prevent them from becoming soggy from the mayonnaise.
Good to Know
Refrigerate assembled burgers in an airtight container for up to 2 days. Store uncooked patties (before cooking) in the fridge for up to 3 days or freeze for up to 1 month.
Form and chill burgers up to 12 hours ahead. Prepare tomato pesto mayonnaise up to 2 days ahead.
Serve immediately after cooking and assembly while rolls are still warm.
Common Mistakes
Do not over-cook the sweet potatoes or they will become mushy and difficult to shape.
Do not skip chilling or burgers may fall apart during cooking.
Do not press seeds too firmly or they may crack and fall off during cooking.
