Braised lamb heart

This was really rather good! No photos, I'm afraid.
 1 packet lamb hearts (Tesco sells packs of 2)
1 tbs plain flour
1/2 cup flageolets
1 onion
2 cloves garlic
2 large tomatoes
1/2 punnet mushrooms
1 chili pepper
1/2 red sweet pepper
1/2 packet "soup mix" vegetables - a mixture of chopped leeks, swede and carrot sold by my local Lidl
1/2 cup pearl barley
1 tbs mint jelly
about 250 ml water
Salt and pepper

Cook the flageolet beans (use any beans you like, but I do like flageolets) - I just put them in the Instant Pot with a bit of bicarbonate of soda, and cooked for 20 minutes, letting them cool naturally. You could use a tin of beans that you have drained and rinsed instead.

Peel and chop all the vegetables, then fry in a little oil until beginning to be soft. Transfer to slow cooker.  Cut the hearts in half and slice them, removing any tuby bits. Fry these in the same pan you have just cooked the vegetables in, adding a little more oil if necessary, and sprinkling them with the flour. Stir vigorously. Then transfer this to the slow cooker, plus the barley.

Deglaze the pan with the mint jelly and water, and season with salt and pepper and any other seasoning you like. Pour this into the slow cooker, stir well, and then cook on auto for about 7-8 hours.
