Notes

  1. Store-bought seitan varies in texture. If too soft, sear longer for chewier texture. If making homemade, add 2 tbsp chickpea flour to gluten for better crumb.
  2. Green/brown lentils hold shape. Red lentils dissolve into sauce. Use green for texture, red for thicker sauce.
  3. This meal contains 14g fiber. If not adapted to high-fiber diets, start with ½ portion and increase gradually to avoid bloating.
  4. Lentils are high in lysine but low in methionine. Seitan is high in methionine but low in lysine. Together they provide complete protein coverage equivalent to meat.
  5. Sauce improves after 24 hours refrigerated as flavors meld. Freezes well up to 3 months. Store pasta separately when meal prepping to prevent mushiness.
  6. Canned tomatoes and seitan can be high in sodium. Rinse seitan before use and choose no-salt-added tomatoes if monitoring blood pressure.
