This dish is a little spicy, enough to feel it, but not enough to make your mouth hot. You can adjust the hot sauce and cayenne pepper levels however you like.
Frozen shrimp is perfectly fine, just be sure to thaw it before beginning. To thaw shrimp quickly, place them in a ziptop bag and submerge them in a bowl of cold water for around 20 minutes. Do not use warm or hot water.
Fire roasted diced tomatoes add an extra element of heat to this dish, but you can easily substitute with regular diced tomatoes if preferred.
