Units Scale
  • 1/4 cup olive oil
  • 2 onions, finely diced
  • 2 red bell peppers, chopped
  • 2 cloves crushed garlic (or 12 teaspoons prepared garlic from a jar)
  • 1 teaspoon Italian Seasoning Blend (or to taste)
  • 4 crookneck squash, halved and sliced into strips
  • 4 zucchini, halved and sliced into strips

  1. Prepare all the vegetables before you start to cook.
  2. In a hot skillet, combine onions, red bell pepper, garlic, Italian seasoning, and oil.
  3. On medium heat, stir and turn frequently so that none of the vegetables scorch.
  4. Cook just until onions are transparent; do not let them brown.
  5. Add the crookneck squash and zucchini to the skillet and gently stir.
  6. Let the vegetables cook, stirring occasionally, until all the squash and zucchini are crisp tender.
  7. Add the tomatoes and cook just long enough to heat them through.
  8. Season the vegetables with salt and pepper to taste and gently toss to distribute the seasonings.
  9. Transfer the vegetables to a serving dish and sprinkle with Parmesan cheese.


Make Ahead Tip: Prepare all the vegetables for cooking up to 1 day ahead of time and store them in Zip Lock bags in the refrigerator until you are ready to cook them. This dish is best NOT reheated.

To use this recipe year round, substitute some of your veggies with whatever is currently fresh and seasonal.
