Step-by-Step Instructions

- Brown the Beef:
- Add ground beef chopped onion minced garlic Italian seasoning salt pepper and red pepper flakes Break the beef into small pieces with a wooden spoon and cook until browned and fragrant which takes about seven minutes Browning builds depth in every spoonful
- Combine the Veggies:

Storage Tips
Let the skillet cool completely before transferring leftovers to airtight containers Store in the refrigerator for up to four days For freezing divide into single servings and wrap tightly to prevent freezer burn I like to reheat leftovers in a covered pan to keep the beef juicy
Ingredient Substitutions
Ground turkey or chicken works well in place of beef for a lighter option If you avoid dairy use plant based cheese shreds or simply leave off the topping Colorful peppers can be swapped according to preference or what is on hand
Serving Suggestions
Add a scoop of sour cream or fresh chopped parsley for extra flavor A crisp side salad or roasted green beans complement the dish and keep the meal balanced Sometimes I serve leftovers wrapped in lettuce leaves for a fun lunch
