Cook the pasta according to the directions on the package, adding the broccoli florets for the last 3 minutes of cooking. Drain well and add the pasta and broccoli back in the pot.
Prepare the cheese sauce while the pasta cooks. In a small saucepan, combine evaporated milk, chicken broth, cornstarch, dry mustard, garlic salt, onion powder and black pepper. Over medium heat, whisk occasionally until mixture comes to a low bowl and thickens. Remove from heat and stir in 1 cup shredded cheese until smooth.
Pour the cheese sauce over the pasta and broccoli mixture and stir until evenly coated. Rewarm pasta over low heat if needed.
Either stir in, or top with, remaining 1/4 cup cheese, sprinkle with bacon bits and serve.
Store any leftover mac and cheese in an airtight container in the refrigerator.

But if don't have elbows, try any short cylindrical pasta like ziti, rigatoni, or corkscrew shapes like fusilli.
