I am hungry and want to start eating a vegetarian diet. Suggest a recipe that I can make tonight. I have zucchini and cheddar cheese in my fridge that will go bad soon, please make use of those two items.
Certainly! Given your situation, I recommend a Zucchini and Cheddar Frittata. Here's a simple recipe you can try for 4 servings (you can adjust the amounts as you see fit):

INGREDIENTS

1 pound zucchini (about 2 small zucchini)
3 tablespoons unsalted butter
⅓ cup finely chopped shallots, from 1-2 shallots
Salt and freshly ground black pepper
8 large eggs
⅓ cup heavy cream
1¼ cup (5 oz) shredded Cheddar cheese

INSTRUCTIONS

1. Preheat the oven to 325°F or about 160°C.
2. Using a food processor or box grater, grate the zucchini. To remove  any excess moisture, place the grated zucchini on top of several layers of paper towels and wring dry. Do this multiple times, if necessary.
3. In a 10-inch cast iron or ovenproof nonstick skillet, melt the butter over medium heat. Add the shallot, grated zucchini, and ½ teaspoon salt; cook, stirring occasionally, until the moisture evaporates and the zucchini is tender, 7 to 8 minutes.
4. Meanwhile, in a medium bowl, whisk together the eggs, heavy cream, a heaping ¼ teaspoon salt, and ¼ teaspoon pepper.
5. Add the cooked zucchini and grated cheese to the egg mixture and stir to combine. Pour the frittata mixture into the pan (no need to wash it), then place in the oven and bake until set, 25 to 30 minutes. Immediately place a dish towel or oven mitt over the pan handle after you remove it from the oven; it's easy to forget that it's hot and burn your hand.
7. Serve warm and enjoy!
