Step 1

Preheat oven to 375 degrees F. 

Step 2

Slice off the stem of the squash. Starting at the top of the squash, slice the squash lengthwise, to create two long halves. 

Step 3

Remove the seeds and guts. Brush some olive oil onto the squash and sprinkle with salt and pepper. 

Step 4

Place squash halves cut side down on the baking sheet and roast for 30-50 minutes, depending on how large your squash is. 

Step 5

Check on it around 25 minutes of baking time--it's ready when it is tender and easy to scrape the strands with a fork.

Step 6

While the squash is roasting, prepare the filling. In a mixing bowl add the chopped avocado, onion, tomato, black beans, and cilantro. Season to taste with lime juice, salt, pepper, and red pepper flakes.

Step 7

Remove squash from the oven and flip over. Sprinkle on, to taste, some chili powder, cumin, oregano, salt, and pepper. 

Step 8

Fill each half of squash with the vegetable filling. Enjoy!
