Ingredients and Substitutions

• YELLOW SQUASH: Yellow squash is considered a summer squash. It is somewhat sweeter than zucchini.
  • Choose smaller squash
  • Harvest early if homegrown
  • No need to peel.
• ONIONS:
  • Either yellow or white onions
• BELL PEPPERS:
  • Use red, yellow, or orange peppers.
  • Green peppers have a stronger, less sweet flavor.
  • Mix colors for visual appeal.
    📌Kitchen Tip📌 Did you know you can chop and freeze bell peppers? Wash, seed, and chop. Place them into a plastic bag and drop them into the freezer.
• MUSHROOMS:
  • White button mushrooms are common;
  • Canned mushroom bits may be cheaper
  • Omit if you preferred
• MILK:
  • Use fat-free, low-fat, whole milk, or evaporated milk.
• CORN:
  • Fresh off the cob is best
  • Frozen is almost as good
  • Canned as a last resort.
• GREEN CHILES:
  • Some green chiles are spicier than others. Start with a 4 oz. jar and adjust to taste. (If you don’t use the whole can, freeze the extra.)
  • Sriracha adds extra heat.
  • Green chiles add spice and a Tex-Mex twist to this recipe.
• STUFFING:
  • Use boxed cornbread stuffing (Stove Top or Pepperidge Farms)
  • If you use boxed stuffing, do not add more salt.
  • Leftover cornbread works, too; freeze and crumble as needed.
    • See recipe notes for how to dry and crumble homemade cornbread.
• CHEESE:
  • Use Cheddar, Monterey Jack, or Pepper Jack for extra spice. Stir in or sprinkle on top before baking.
