Preheat oven to 180C fan.

Place tomatoes in a small roasting tin and roast in the oven for about 15 minutes so they are just beginning to split.

Boil a kettle and fill a large pan with the boiled water, bring back to the boil and add the vinegar.

Cut the avocados in half and scoop out the insides.

Place avocado in a bowl with the lime juice and mash together, but leave slightly chunky.

Turn on your grill, drizzle the olive oil over the four slices of muffin and toast until lightly browned under the grill.

Whilst keeping an eye on your toasting muffins poach the eggs in the pan of boiling water for about 3 minutes, (you want the yolks to still be slightly runny). Remove with a slotted spoon onto a plate.

Spread the toasted muffin halves with the smashed avocado, place the poached eggs on top and divide the cherry tomatoes between the two plates.

Season and serve.
