Cajun Shrimp with Peppers and Onions

By Rachel Stuck, RDN

Mildly spicy Cajun seasoning pairs perfectly with shrimp, peppers and onions. Shrimp is low in calories, yet high in protein and a good source of several nutrients including selenium, iron, calcium and vitamin B12.

When purchasing shrimp look for shrimp that is either wild-caught or farm-raised, antibiotic-free to ensure freshness and good quality.
