Spinach: Fresh spinach adds color and nutrients; opt for organic if possible.

Bell Peppers: Use any color you prefer—red, yellow, or green—to add sweetness and crunch.
Milk: Whole milk provides creaminess; feel free to use almond milk for a dairy-free option.
Salt and Pepper: Essential seasonings that enhance all flavors; adjust according to your taste.
