The evils of garlic powder

So this started out with the best of intentions
I read the comments for the recipe and it said to use less of the spices and to bake the darn thing in the oven if you don't have a grill.

I put only a teaspoon of garlic powder and a good sprinkle each of salt and black pepper.
I was drinking a bit at the time so maybe it was more than a sprinkle.
Anyway the zucchini now go in the oven and I cook some carrots and potatoes in a skillet.
It comes out....well lets say a little strong.
I made rice to eat it over and with the rice it is OK
not getting a great review this.
possibly that has something to do with being drunk and cooking just for myself but I am gonna blame the garlic powder.
With real garlic you know how much is appropriate but who knows how much is too much powder? Not I clearly.
