Assemble each burger by layering the spread, greens, patty, onion jam, and any optional toppings for a taste of French comfort cuisine. For a nut-free version, substitute sunflower seeds for walnuts and use sunflower seed butter in the spread. Use certified gluten-free oats and buns if needed. The onion jam and cashew spread can be prepared up to 3 days ahead.
