Peas was a staple in Medieval times. I thought you would like to see one of the dishes they would have eaten. It don’t look bad at all. Enjoy.
Take green peas, and boil them in a pot; And when they are broken, draw the broth a good quantity through a strainer into a pot, And sit it on the fire; and take onions and parsley, and hew them small together, And cast them thereto; And take powder of Cinnamon and pepper and cast thereto, and let boil; And take vinegar and powder of ginger, and cast thereto; And then take Saffron and salt, a little quantity, and cast thereto; And take fair pieces of pandemaine, or else of such tender bread, and cut it in fair morsels, and cast thereto; And serve it so forth.
From Harleian MS. 4016, Volume II
Once Upon a Paradigm 
Pease porridge hot, pease porridge cold,
Pease porridge in the pot, nine days old;
Some like it hot, some like it cold,
Some like it in the pot, nine days old.
Well now we know what pease porridge looks like. I am not sure if I would want to look at it after 9 days?
I read that they used to just leave it near the fire and mix in new pieces of meat and vegetables as available. Sounds yummy.
It makes you wonder how the human race survived. They must have had a stronger immune system then we have today.
