Spicy Southwest Salad Dressing

Add a little Tex-Mex flavor to your greens…

If you have Ranch dressing at the ready, a decently stocked spice rack, and a few common kitchen ingredients, you’re ready to make a delicious spicy Southwest salad dressing. This is a 5-minute “whip it up” recipe that’s still mighty Tex-Mex tasty for how simple it is. Try it with a simple green salad or use it as the dressing base for a Tex-Mex salad bowl featuring beans, corn, greens, and chicken.

Chili powder provides that Tex-Mex flavor, though it’s not known for its spiciness (being a mix of spices). The heat in this spicy Southwest salad dressing comes from cayenne pepper powder. Adjust it based on your spice tolerance.

Want it spicier? Add a little more cayenne pepper powder, to taste.

Excellent! I made it to go on top of some homemade black bean burgers and a side salad, was perfect. And nice spice level.

This salad dressing is wonderful. It is pretty spicy and I might cut down a tiny bit on the cayenne pepper powder next time.
