Boston beans are one of the easiest meals that you can make as basically everything just gets chucked in the slow cooker and left for the day! It can be enjoyed as a meal on its own like a casserole or as a side dish instead of the usual, boring tinned baked beans.

If you follow Slimming World, Weight Watchers (WW), Noom or any other weight loss plan you can usually count this as free or easily within your allowances due to lean meat being used, of course always check your plan for advice.

Firstly, gently fry the diced pork for five minutes, then add the onions and peppers and fry for another couple of minutes. Add everything else then simmer for around 30 minutes.

Adaptions you can make to the Boston beans recipe

If you are not a fan of mixed beans then simply swap these for more haricot beans. Whilst these look different on their own they are actually the same beans used in an ordinary can of baked beans.

If you prefer to use sausage, gammon or bacon in this recipe it would work just as well. To ensure it is still healthy be sure to use low-fat sausages or remove the fat from gammon or bacon.
