Cook Pasta according to directions on package. Before draining, reserve about a cup of the starchy pasta liquid.
In the meantime combine Sour Cream, BBQ Sauce, Homemade Ranch Dressing, Mayonnaise, Black Beans, onion, tomatoes, sugar and vinegar. Drain pasta and allow to cool for about 5 minutes. Add to the salad ingredients and stir to combine. Pour in the pasta water until the pasta seems creamy. I usually use about ½ cup or a little more.
Notes
This Southwest Pasta Salad is a perfect make-ahead pasta salad. It's one of those dishes that tastes better the next day. It will keep in the refrigerator, well sealed, for three to 4 days.Pro Tip: Why is pasta water good for pasta sauce? Don't throw all of that pasta cooking liquid down the drain, It’s liquid gold. It’s a must to add to any sauce for any pasta dish. It’s high in starch and this salty starchy water helps the sauce cling to the pasta while helping to thicken the sauce. It turns any pasta dish into a luxurious pasta dish.Variations:
Add 1 cup of sweet corn. Use frozen (that's been thawed) or canned.
To heat things up, add a 4 ounce can of chopped green chile peppers.
