Ingredients

  • 2 small yellow summer squash, sliced
  • 1/4 cup chopped onion
  • 1/2 teaspoon salt, divided
  • 1 large egg
  • 1/4 cup mayonnaise
  • 2 teaspoons sugar
  • Pepper to taste
  • 1/4 cup shredded cheddar cheese
  • 2 tablespoons crushed cornflakes
  • 1-1/2 teaspoons butter, melted

Directions

  1. In a small saucepan, combine squash, onion and 1/4 teaspoon salt. Cover with water. Bring to a boil. Reduce heat; simmer, uncovered, until squash is crisp-tender, about 2 minutes. Drain.
  2. In a small bowl, whisk the egg, mayonnaise, sugar, pepper and remaining salt until blended. Stir in cheese and squash mixture. Transfer to a greased 2-cup baking dish. In a small bowl, toss the cornflakes and butter; sprinkle over top.
  3. Bake, uncovered, at 350° until golden brown and bubbly, 25-30 minutes.
