title: Django - Create the equivalent of a "cross-join" query with the Django ORM
body: <p>I have two Django models with are related to each other through a many-to-many relationship.</p>
  
  <p>I need to list the cross product of both tables.</p>
  
  <p>Let say for simplicity's sake that the two models are Pizza and Topping.</p>
  
  <p>I would like the query to return something like this:</p>
  
  <pre><code>pizza_name    topping
  ---------------------
  all dressed   cheese
  all dressed   mushrooms
  all dressed   onions
  all dressed   peperoni
  all dressed   pepper
  reddit        cheese
  reddit        peperoni
  reddit        bacon
  reddit        baconbits
  </code></pre>
  
  <p>The amount of data will be very large and I absolutely need to use count and slices so I can't simply iterate a model and treat the data as I go along.</p>
  
  <p>Any idea how I should proceed?</p>
