# Expert Advice:

01 -
  • Everything roasts or warms on its own, so you can chop avocado and call it multitasking.
  • The contrast between smoky sweet potato and tangy lime beans makes every bite feel intentional, not thrown together.
  • It looks impressive enough for company but requires exactly one pan and a saucepot.
  • You can make it vegan, keep it vegetarian, or load it with hot sauce depending on who is eating.
02 -
  • Overcrowding the baking sheet will steam the sweet potato instead of roasting it, and you will lose those caramelized edges that make this dish sing.
  • If you add the lime juice while the beans are still on the heat, the acidity can turn them slightly metallic, always stir it in off the flame.
  • Tostada shells go stale fast once opened, so store leftovers in a sealed bag with the air pressed out, or they will taste like cardboard by morning.
03 -
  • If your sweet potato cubes are not caramelizing, your oven might be running cool, bump the temperature up by 25 degrees and give them an extra five minutes.
  • For a vegan version, skip the feta and add a handful of toasted pepitas for salty crunch and healthy fats.
  • Always taste the bean mixture before assembling, it should be aggressively seasoned on its own because the tostada shell and avocado will mellow everything out.
