Let leftovers cool then cover and refrigerate for up to three days It reheats well in the oven or microwave If making ahead complete up to the baking step then chill and bake right before serving to keep that fresh melt

Ingredient Substitutions

Try sweet potatoes if you are out of regular ones Use kidney beans or chickpeas instead of lentils Any vegan cheese with a robust flavor can stand in for cheddar You can even use fresh sautéed veggies if freezer ones are low

Serving Suggestions

Bring it to a potluck and watch it disappear quickly Serve with a crisp green salad or just pile into bowls for a comforting dinner night I love drizzling with a dash of hot sauce for a little zing
