Recipe Notes
- Weigh your protein raw for the most accurate macros.
- Season in layers: a little salt at each stage beats a lot at the end.
Storage Tips
Store in an airtight container in the refrigerator for up to 4 days. Reheat gently, covered, until warmed through.
Meal Prep Tips
Double the batch and portion into single-serve containers while everything is still warm. Cool uncovered for 15 minutes before sealing so condensation does not water down the sauce.
Recipe Variations
- Swap the protein one-for-one with chicken, turkey, shrimp, or extra-firm tofu.
- Add a cup of chopped vegetables to raise the fiber without changing the cook time.
