  1. Put the onion in a bowl and cover with half the lime juice and a good pinch each of sugar and salt. Leave to soften while you get everything else ready.

  2. Mix together the crabmeat, spring onions and half the chilli. Season with black pepper and set aside. Mash the avocado with the remaining lime juice, garlic and some seasoning. You can leave it quite chunky or mash it until smooth. Stir in the rest of the chilli.

  3. Bend each tortilla in half and toast in a toaster for 1 min. Put on 2 plates and top with the salad leaves, then mashed avocado. Finish with the crabmeat and drained pickled onion. Serve with lime wedges for squeezing over.

Had these for lunch today and they were delicious, although I do have a few comments.

1. I felt the red onion really overpowered the crab (and everything else actually) so while it is a lovely flavour I might omit it next time.

2. Make sure to season your guacamole well - I forgot and it was lacking

3. Be sure not to overdo your tortillas in the toaster - 1 min on medium heat is perfect, any longer and they will go hard and spoil - but what a brilliant idea to heat in the toaster - I usually do mine in the microwave - total convert now

4. This recipe makes enough filling for 4 tostadas, which is handy if your husband has hollow legs like mine does and needs a more hearty lunch

All in all though a hit in our house!!

Made these crabocado tastas yesterday for my dinner! Never used crab before...
After I'd plated up, I had some leftover crab and onion mix, so I tried the two together, aaand it tasted a bit odd. But then, once topped on savoury pancakes over the easy guacamole, it turned out really nicely! You can see my result here:

Delicious, light, healthy and quick. Couple of small things though:
1. I doubled the avocado as 1 wouldnt and didnt go far.
2. They were difficult and messy to eat so we folded them in half. Much easier and less messy.
