Caramelised Red Onion, Feta and Bacon tart

Caramelised Red Onion, Feta and Bacon Tart

Don't you just love a good tart? I certainly do and always make sure I've got some sheets of puff pastry stashed away in my freezer to quickly satisfy any tart cravings that may occur.

Part of the reason I love tarts is that they are a great vehicle for using up odds and ends. I know I told you last week that Frittata's were the mother of leftover vehicles...but tarts come pretty close too.

So, the tart in question involved slowly caramelising some sliced red onions in balsamic vinegar and brown sugar until sticky and syrupy, my house smelt amazing. Then all was required was some assembly work....unrolling out the puff pastry sheet, spreading over the onions and bacon and crumbling over the feta. So simple but so so tasty. Sun dried tomatoes and goats cheese would work well as an alternative, as would olives and grated cheddar. What are your favourite tart toppings?

    The tuna pasta salad you had on your food plan this week is it similar to your easy pasta salad?

  6. Looks delicious! I like to make something very similar, only as pizza!

  7. Looks delicious. I have to say I never make tarts but may have to try this one. I usually do combinations like this in either a fritatta or pizza.

  8. This is basically what we had on Christmas Day, missing out the bacon and adding in gravy, roast potatoes and lots of veg. It was lovely!

  9. Looks yummy and easy to make! I'll put it on my list and will give it a go soon!

  10. great recipe, similar to the courgette tart I made recently but caramelised onions and feta is a perfect combo!

Microwave meals are back and this is a fab bung it in the microwave recipe that's a real lifesaver when time is short...or when you don't have the use of an oven! People don't tend to use their microwaves for actually making meals but I've found I can do quite a lot in mine...veggie chilli, risotto's, as well as this really flavourful jambalaya with chorizo and red pepper.

Honey and Peanut Butter Flapjacks

These flapjacks are now my official weekday grab and go breakfast. I make a big batch on Sunday evening and I'm all set for the week. Oddly I don't really like peanut butter but it works well in this recipe. You can always substitute it for an extra 100g of ordinary butter if you wanted. A handful of raisins makes a nice addition too.

Golden Syrup and Oat Cookies

My Mum used to make these moreish buttery cookies all the time and they bring back great childhood memories of licking the syrup spoon clean. They take less than 10 minutes to make and 10 minutes in the oven so they are super speedy for busy days...and most importantly the kids love them.

Slow Cooker Chilli Con Carne (No Browning Required)

My slow cooker is my best friend on week days, especially when it's a recipe like this Chilli Con Carne that requires NO pre browning of the meat. It takes all of 3 minutes to 'make' before leaving the slow cooker to do all the hard work during the day. Then, when you get in from a long day at work and the kids are starving, all you need to do is cook some rice and grate some cheese! If you have any leftovers you can stir them into cooked pasta the next day along with some creme fraiche and grated cheddar for a super simple chilli pasta bake. Everyone in my house loves this recipe...well apart from the kidney beans which the kids aren't too keen on!

TOP TIPS FOR MAKING SLOW COOKER CHILLI CON CARNEIf your children actually like kidney beans (mine usually pick them out) add another tin for extra fibre.Instead of adding the spices separately you could buy a Chilli Con Carne spice sachet (e.g. Schwartz) and use that instead.If you like a bit of heat add a tsp of dried chi…
