Method
 

Grill the Veggies
  1. Preheat grill on medium heat. For yellow squash, chop the tops up into bite size pieces and add to a vegetable grilling basket with red bell pepper and onion. Coat all vegetables with an olive oil drizzle, salt, and pepper. Place on grill with squash halves and grill 10 - 20 minutes (will depend on grill size and space). Flip halfway through and cook until there are grill marks on each side and veggies have softened. Set aside to cool.
Make the Filling
  1. While the vegetables are on the grill, make the filling by simply mixing together all of the ingredients in the Filling subheading above. Set aside.

Assemble the Casserole
  1. When the squash has cooled chop the halves in to bite size pieces (you may have some extra). Mix with the grill basket items and form a layer in the bottom of the casserole dish (can make as deep in dish as desired, just leave room for filling and topping).
