Yep, I was eating fried eggs one by one last test to see if I could trigger the 11 meals achievement, and though I got well beyond 11 meals, I could not.
Judging from the badge, meals may be only from a knife and board or a mike tyson grill. I'd also suspect awesome pot.
The Bonbon Vivant 101 meaL badge has been tied to eating 101 meaT ever since the badge was introduced, long-time known bug. I have the badge and there's no way I ate 11 meals, let alone 101.
Just to note that I must have made 100s of meals with every cooking instrument this test and gobbled them up, but never received the 11 meal or the 41 meal award. I'm very certain that I ate 11 meals each from the knife & board, the fry pan, the grill, and from the awesome pot.
