Garlic and lemon prawns with zoodles

I love zoodles (zucchini noodles) and I keep trying to find easy and delicious recipes to have it more often. This time I found a very easy recipe at fastpaleo.com but I changed the recipe a bit.

Ingredients
serves 2
2 medium zucchinis
12-15 large prawns, peeled and deveined
½ tbsp extra virgin olive oil
2-3 cloves garlic, crushed or grated
1 tbsp minced fresh parsley
Zest from one lemon
Juice from ½ lemon
½ avocado, mashed
pinch salt and pepper
1 tbsp butter
2 cups baby spinach

Mix together olive oil, avocado, crushed garlic, lemon juice, zest, parsley, and salt and pepper to taste.
Make noodles from zucchini using a julienne peeler or cut into thin strips. Place zoodles in a strainer or colander. Sprinkle noodles with salt, toss and let sit for 10-20 minutes to release liquid.
Drain water from zucchini and pat dry with paper towels. Heat butter over medium heat and have all your ingredients ready to go.

Add shrimp and cook for about 30 seconds. Flip the shrimp, cook for another 30 seconds, then add the zoodles. Toss a few times to coat. Add spinach, continue tossing gently and cook for a minute or two until zoodles are cooked to preference and shrimp is cooked through. Turn off the heat and mix in the avocado mixture.
