Ingredients for 4 servings:
1. 1 large zucchini, quartered lengthwise and sliced 1/4 inch thick
2. 2 medium yellow squash, quartered lengthwise and sliced 1/4 inch thick
3. 1 medium sweet onion, quartered and sliced 1/8 inch thick
4. 3 plum tomatoes or 3 roma tomatoes, seeded and coarse chopped
5. 1 lemon
6. 2 tablespoons olive oil
7. salt and pepper, taste

Directions:
1. Preheat oven to 400 degrees F.
2. Place zucchini, yellow squash, and onion in a 9 x 13 pan.
3. (I use a disposable one.) Drizzle the olive oil and squeeze the lemon juice over the vegetables.
4. Add salt and pepper to taste.
5. Toss to coat the vegetables with the seasonings and oil/juice.
6. (I use my clean hands, takes about 5 seconds.) Sprinkle the chopped tomatoes on top.
7. Place in preheated oven for about 20 minutes, stirring after 15 minutes.

Enjoy your meal!
