Cut bacon into thin slices (with knife or kitchen scissors). Thinly slice red onion. Cut zucchini in bite sized chunks. Peel carrot and cut into chunks. Set aside.
Place bacon pieces in skillet with thin slices of red onion. You don't need to spray skillet, because the bacon will provide it's own "oil" as it cooks. Sauté on medium heat until bacon is crisp and fat (bacon grease) is rendered into skillet.
Add green and yellow zucchini (cut into bite sized chunks), and carrot to skillet. Season with a pinch or two of salt and pepper (to taste). Stir and cook in the bacon "drippings" for 4-5 minutes on medium heat, stirring occasionally, until zucchini is slightly browned, and tender-crisp (NOT soggy!). Add minced garlic, and stir to combine. Cook for an additional minute, stirring often. The reason to put the garlic in at the last minute is so that it does not burn (which makes the garlic taste bitter- no one wants THAT!).
Sprinkle grated sharp cheddar cheese over the top of the veggies. Do NOT stir. Turn off heat. Place a skillet lid over top of skillet for about a minute (this will melt the cheese). Remove skillet lid, and you will see the cheese has melted. Use a spatula and transfer veggies to individual serving plates. Serve hot... and enjoy!
