Think about how cheap you can get fast food, chips, candy bars, hot dogs, sugary drinks, etc.
Not denying they are readily available. I don't really eat fast food regularly. I'll stop at a Wendy's or something for a burger on a road trip, but I hate eating and driving so that's rare.
What's a Big Mac meal these days? 6 bucks?
The other night I made fajitas with brown spanish rice and chilied (dusted with cumin, oregano and chili powder) grilled vegetables.
1 pound top sirloin was 4 bucks.
About 50 cents of rice
2 bucks worth of vegetables.
Lettuce from the garden to take the place of tortillas.
That fed five.
I don't know. I guess unhealthy stuff can be cheaper, but like I said, it's generally unsatisfying to me, and I always want more.
