Pea and Lemon Risotto

I adapted this recipe from Martha Stewart Living.  If you are going for dairy free, just skip the parmesean, it won't change the flavor or texture at all.

• 6 cups vegetable stock, low sodium may be ideal
• 1/4 cup olive oil
• 1 small onion, finely chopped
• 1 cup Arborio rice
• 1/2 cup dry white wine
  
  
  2 cups of peas (frozen or fresh)
• 1 teaspoon grated lemon zest
• 2 tablespoons fresh lemon juice
• 1 cup chopped fresh flat-leaf parsley leaves
• 1/2 cup finely grated Parmigiano-Reggiano
• Coarse salt and freshly ground pepper
  
  
  Directions:
  
  
  1. Bring stock to a simmer in a medium saucepan.
  2. Heat 2 tablespoons oil over medium heat in another saucepan. Cook onion, stirring frequently, until soft, 6 to 7 minutes. Add rice, cook, stirring, until edges are translucent, 2 to 3 minutes. Add wine; cook, stirring, just until evaporated.
  3. Add 1/2 cup hot stock; cook, stirring, until almost absorbed. Continue adding 1/2 cup stock in this manner until liquid is creamy and rice is al dente, about 20 minutes total (you may not need to add all the stock). Add asparagus with the last addition of stock, and the peas about 1 minute before risotto is done.
  4. Remove from heat; stir in lemon zest and juice, parsley, cheese, and remaining 2 tablespoons oil. Season with salt and pepper. Serve immediately with additional cheese and lemon zest.
