Yogurt Dip for Vegetables

I roasted some winter vegetables and wanted something to spruce up the meal, so I read a variety of recipes online for dips, and ended up making this up. It's pretty good. The key is super fine chopping. It would also be good with crudite too.

• 1 1/2 c plain yogurt
• 3 tsp mustard (yellow with some kick of some sort is best)
• dash of salt
• dash of garlic powder
• good heaping of black pepper
  
• 3 tablespoons parsley, finely chopped

Mix it up and serve immediately.
