- 2 cups diced bell peppers (any colour)
- 3 cloves garlic, minced

- 1 tsp smoked paprika
- 4 cups low-sodium chicken broth
- 1 (14.5-oz) can diced tomatoes with green chiles (undrained)
- 4 oz cream cheese, softened
- ½ cup plain Greek yogurt (optional, for extra protein)
- 1 Tbsp fresh lime juice
- Salt & freshly ground black pepper, to taste
Optional Add-Ins:
- 1 cup chopped zucchini or cauliflower rice (to bulk it up without carbs)
- Sliced jalapeño or chipotle powder for extra heat
- Toppings: shredded cheddar, avocado slices, chopped fresh cilantro

Step-by-Step Instructions
Step 1: Sauté the Aromatics
Heat olive oil in a large pot over medium heat. Add the diced onion and bell peppers and sauté about 4–5 minutes until softened. Add the minced garlic and cook for another 30 seconds until fragrant.
Step 2: Season & Build the Base
Stir in the fajita seasoning and smoked paprika, coating the veggies evenly. Pour in the chicken broth and the can of diced tomatoes with green chiles (including juices). Stir well to combine.
Step 3: Add Chicken & Simmer
Add the shredded (or raw and then shredded) chicken to the pot. Bring everything to a gentle boil, then reduce heat and let simmer for about 10 minutes this lets flavours meld and chicken absorb the zest of the broth.
Step 4: Make It Creamy
Lower the heat. Add the softened cream cheese and stir until it melts into the broth and becomes smooth. If you’re using Greek yogurt, stir it in now for extra protein and creaminess do this off heat or on very low to prevent curdling.

Step 5: Finish & Serve
Stir in fresh lime juice and season with salt and pepper to taste. If you added zucchini or cauliflower rice, cook another 2 minutes until they’re just tender. Ladle into bowls and top with optional cheddar, avocado or cilantro for crunch, freshness or richness.
