Add canned tomato and seasonings to cooked meat and simmer for about 5 minutes.
Place the sliced squash at the bottom of a 9×13 inch baking pan. Place meat mixture on top of squash, sprinkle grated cheese on top.
Bake in preheated oven for about 25 minutes.
Notes
Green chilis can be added to spice things up. You can sprinkle 2 to 3 sliced green chilis if desired.Yellow squash releases water as it cooks. Salting the squash after it's sliced and letting it sit can release the water prior to cooking. Or you can grill it first before using.
