Sounds delicious- but not no carb I’m afraid, it may be low carb depending on how much of the ingredients you used that contain carbs, that would be the peppers, onions, cottage cheese. Also stress and if the heavy work was lifting then both of those can raise your blood glucose.
Next time you make it weigh your ingredients and log the carbs and then test before eating and 2 hours after, maybe without your stress and yard work it may be ok.
I make similar but I go light on the onions and peppers, usually use spring onion and some onion powder and I use hard cheese grated as I find cottage cheese quite high in carbs.
