Slow Cooker Ham, Spinach and Ricotta Lasagne

This slow-cooker lasagne is so easy to make, you'll be looking for the catch (we promise there isn't one!). The spinach only needs a moment in the microwave, before it's ready to combine with ricotta and ham for the mouthwatering creamy filling. Layer up with lasagne sheets and herby passata, until you've made three tiers of Italian-inspired heaven. When the Cheddar is sprinkled over, that's your cue to slow-cook until the pasta is tender with a melty top.
