# Expert Advice:

01 -
  • It comes together in about an hour and tastes like you spent the whole afternoon cooking.
  • Every vegetable stays distinct but somehow works together, like a choir where everyone gets their moment.
  • The crispy breadcrumb topping is secretly the best part, and it's vegan—so no one feels left out.
  • You can make it ahead and reheat it, which means less stress when people arrive.
02 -
  • Don't skip rinsing the lentils and quinoa—this removes the bitter coating and makes everything taste cleaner.
  • The spinach and lemon juice go in only after the first bake, because raw spinach would turn into sadness if it spent the whole time in the oven.
  • If your skillet isn't oven-safe, transfer everything to a casserole dish before the first bake; the cooking time stays the same.
  • The topping needs that olive oil to crisp up—breadcrumbs alone will just sit there looking sad and pale.
03 -
  • If you're cooking for a crowd and want to make this ahead, assemble everything except the topping the night before, then add the breadcrumb mixture right before baking.
  • A splash of white wine or vegetable broth instead of some of the water makes the whole thing taste more intentional and sophisticated.
