Wendy's Copycat Chili Seasoning Mix, plus chili recipe, at Grandma Bee's Recipes.
Tweaks: Since I had only a pound of meat, I cut the seasoning in half. I kept the other amounts about the same. (Two cans of beans, though, not four.)
Verdict: I have no idea if this tastes like Wendy's chili. It's what I'd call diner or homestyle chili, not overly ambitious but tasty just the same. Easy to make in the slow cooker, and would work well as a freeze-ahead.
