Best Ever Spinach, Carrot & Leek Soup

I don’t know about you, but for me soup and winter go hand in hand. The minute the weather gets colder I’m straight into the kitchen, blitzing up all manner of different ingredients to test out new and exciting soup flavours to keep me warm and interested on these long cold days! This Spinach, Carrot & Leek Soup was the result of one of my recent meal prepping days, and man does it taste good!

Is This Soup Slimming World Friendly?

I’m doing my best to stay on plan as we get closer to winter, so for me it’s essential that I’m creating ‘on-plan’ Slimming World friendly recipes to keep me going. This soup is not only 100% syn free on Slimming World, it’s also super nutritious, as it’s high in protein, iron and vitamin C, not to mention all sorts of other essential nutrients. If you’re a fan of syn free Slimming World soups, check out the other varieties I’ve put together here.

Time To Get Meal Prepping?

If like me, you lead a hectic, occasionally disorganised life, this is an excellent option for meal prep! It’s not just because you can make it in bulk, freeze it and take it to work, but soup also doesn’t feel like meal prep. If you have ever meal prepped before, you’ll know that sometimes it can get a bit boring. I love it as much as the next girl, but occasionally another week of rice, veg and meat packed tight into old takeaway containers can feel a tad on the dull side. With soup, however, life suddenly gets interesting and because soup is just soup, it doesn’t seem like a big meal prep activity. Maybe it’s just me, but it can provide a great change, particularly as the weather gets cold! Spinach - Carrot - Leek - Soup - Slimming World - Healthy - Syn Free

Slimming World Meal Planning

This is the perfect addition to your meal plans, whether you’re meal prepping or cooking every day. Ever since I’ve been doing Slimming World I’ve found that creating meal plans can be a total lifesaver. It’s definitely not something I do every week, but when I’m anticipating a particularly busy week at work, or know that I’m going to end up with a few evenings off plan, a meal plan can make all the difference to help me stay on plan. If you find meal plans helpful, but don’t know exactly where to start, these meal plans I’ve put together might help!
