Step 1

Drizzle a small amount of vegetable oil in a large skillet over medium/medium-high heat (6/10 on the heat scale.) Add half or a third of the sausages (depending on how big your skillet is,) then brown for a minute or two on all four sides, or until golden brown, then transfer to a 6-quart crock pot (sausage does not need to be cooked all the way through.) Repeat with remaining sausage then add to crock pot.

Step 2

Turn heat up to medium-high then add onions to skillet, season with salt and pepper, then saute until just beginning to become tender, 3-4 minutes. Transfer to the crock pot.

Step 3

Add bell peppers to skillet, season with salt and pepper, then saute until crisp tender, 4-5 minutes, adding a drizzle more oil if necessary to keep peppers from burning. Add garlic then saute for 1 more minute, and then transfer peppers and garlic to crock pot.

Step 4

Add red chili pepper flakes, a little pit of salt and pepper, tomato sauce, crushed tomatoes, and chicken broth to crock pot then cover and cook on low for 5-6 hours or until sausages are very tender. Serve over pasta or inside rolls with provolone cheese on top.
