Equipment

Enameled dutch oven
Heat diffuser
Cutting board and knife
Freezer-safe containers

Ingredients

Dish A *

100 g onion, diced
50 g celery, diced
50 g green pepper, diced
0.5 bird's eye chili, thinly sliced

Dish B

3 g salt
1 g black pepper

In Their Cans

800 g canned diced tomatoes

* larger than my standard 90ml prep dish

Steps

Combine everything in a dutch oven and bring to a simmer over medium heat.
Drop to low (use the diffuser) and cook uncovered for 60–90 minutes, stirring occasionally, until the vegetables are tender and the liquid has thickened slightly. Remove from heat — the dutch oven is done.
Cool to room temperature, then portion into freezer containers.
