Warm Kielbasa Spinach Salad

I'm a sucker for spinach, which I consume on a daily basis on one form or another (iron? calcium? folic acid? lets hear it for green leafy veggies!). So, obviously its my go-to basis for any form of salad, but I think it especially stands up well to salads with warm toppings. This salad was inspired by the French Lentil Salad and is similar; this version is very summery, light(ish), and all the toppings can be made on the grill.
Dressing (single serving):
-1.5 tbsp grainy mustard
-1.5-2 tbsp red wine vinegar
-pinch salt
-2 pinches pepper
-tad bit of garlic

Toppings:
-washed spinach leaves
-grilled bell pepper (I like yellow)
-Jenny-O lean turkey kielbasa, cut in half lengthwise, cooked on the grill until hot and splitting
-scallions, if you like, grilled
Basically, make a bed of spinach, top with some chunks of kielbasa, sliced veggies, and the dressing. It could definitely serve 4, and your choice of veggies is your own, but I like the simplicity of just the peppers. At any rate, you're done! Eat and enjoy!
