I think tacos are the most perfect food on the planet. If there is one food I could never get tired of it is tacos. I've always loved them since I was a kid and my mom would cook them for me. At first it was purely sour cream and cheese as toppings. As I got older I'd experiment. I loved putting french fries and creamed corn on them for sweetness. When I grew up I went back to traditional toppings.
If you want a cheap and quick meal cook tacos. It takes me less than 30 minutes to whip up some meat with some taco seasoning. It's not gourmet but it's dog gone good. I have tacos a few times a week when I'm busy. I never get tired of eating tacos. They are my favorite food.
