Step 1

Preheat oven to 350 degrees.

Step 2

After the spinach is defrosted (easiest way is to just pop it in the microwave for a few minutes until defrosted but not super hot), squeeze it thoroughly between a few layers of paper towels to remove as much excess water as possible.

Step 3

In a large mixing bowl, combine the spinach, chopped artichoke hearts, roasted red pepper, green onions, and garlic. Set aside for a moment.

Step 4

In another medium mixing bowl, mash the avocado. Add the mayo, lemon juice, salt, onion powder, and pepper, and stir until combined.

Step 5

Add this mayo/avocado mixture into the large bowl with the rest of the ingredients. Stir until everything is well combined, and then pour into a casserole dish.

Step 6

Bake at 350 degrees for about 20 minutes, until everything is hot.
