I have just started doing a meal planner. It's a work in progress. I decided to categorise each day as something and then pick recipes to cook. I have also included what I picked for this week.

Mon - ? Haven't decided yet. (Lemon & Herb Pasta & Chicken Salad - was sunday's meal but we got invited to the in-laws)
Tues - Fish Night (Crumbed fish & salad wraps)
Wed - Chicken Night (Chicken Schnitzels & Salad)
Thurs - Steak Night (Pork Chops with vegies)
Fri - Slow Cooker Day (Cheats Chicken Cacciatore from Best recipes)
Sat - Stir Fry Night (Had planned a curry but DH has other plans this week so will prob have sunday instead)
Sun - Roast/Pasta Night (Spag Bolognaise - will prob have monday due to sat night)

This is only my second week but so far it's working well.
