Chickpea tagine with tomatoes, onions, carrots, gren beans, apricots, flaked almonds, smoky spices and wholewheat couscous.
Savoury crumble. Baked root veg in mildly spicy tomato sauce, topped with oat and nut spiced crust.
Veggie chilli is lovely - no need for quorn - just kidney beans or rose cocoa beans or black turtle beans with tomatoes, onions, peppers, smoky chilli and paprika, served with brown rice. You can add fresh guacamole or sour cream if you want but not necessary if you are keeping costs down.
Wholegrain carbs such as brown rice or wholewheat couscous are good as they combine with other ingredients, especially nuts or pulses, to create a perfect protein, so your DH shouldn't avoid them entirely.
