So.. here's the recipe for Chili for 75
5 lbs (more or less) of hamburger - fried
5 (or more) large onions, diced and fried with the hamburger meat
1 really large can (100 oz) of diced tomatoes (I made a mistake and bought crushed tomatoes this time instead, so that's what I used, but I prefer the diced tomatoes).
12 - 19 oz cans (540 mL) of kidney beans (I could have bought the two 100 oz cans, but the smaller ones were cheaper. For that matter, I could have soaked the kidney beans and done it from scratch, but the cans worked out to the same price and much less work.)
Chili powder to taste (about 1/2 cup I think).
Now it's possible to add lots more ingredients (I like mushrooms, for example, but not everyone does), but that's the basic chili recipe. Because I don't have a pot big enough to combine all this, I used all of my slow cookers; the three small pots and my two big pots - and have them plugged in throughout the house because if I plug them all in the kitchen I'll blow a breaker. I cooked the hamburger in batches in my largest frying pan with the diced onion and divided it among the slow cookers. I layered things in the slow cookers; a couple cups of tomato stuff in the bottom, then the hamburger meat with the onions, then the chili powder, then the cans of beans (smaller slow cookers got 2 cans, larger ones got 3), then more tomato stuff, stir well.
I'm quite pleased with myself. This weekend I was doing the planning for making the chili and was thinking that it was a real pain that my largest frying pan didn't have a lid that fit it. So I measured it - it's 12" in diameter - and when I was a Great Canadian Wholesale (which is where I bought the ingredients for the chili), I looked in their commercial cooking section and bought a pot lid the right diameter. It fits just right and I'm happy! (I need to mention that the meat was all donated.)
