>>21502982 (OP)add more water and stir and it will homogenize, u should have plenty of binder in there
when probably bound it wont be perceived nearly as "greasy" as you see it there
it's a side effect of inexperienced cooks
my ground taco meat improved drastically when i learned how to keep all the fat and make it a consistent porridge texture without grease breaking out
one technique i like especially for meat slops like this is to add a few tablespoons (doubt you'll ever need more than a cup) of textured vegetable protein fine crumbles. you can even grind it up into powder if you want
it lets you bind fat and juices/water together much more easily. you'd be using it like you would flour
you can add flour as well but too much flour changes the texture of the slop as well, i find tvp (textured vegetable protein) doesn't alter the flavor/profile in a negative way until it starts to exceed like 30% of the mass of real meat you started with
