... that I can probably get from Morrisons please?
Will put out a blanket / rug and light some tea lights to make it a bit more atmospheric.

Is this for kids? Or a date? Context needed.

Baked Camembert with crusty bread. Or in crusty bread.

Little salad bits, stuffed tomatoes etc, usually on a multi offer.

Sliced bakery sausage rolls.

Pasta salad box.

Morrisons have a great deli.

Jam
An evening at home with boyfriend - don't live together.

Agree with pp - context needed.
In the meantime - pink lemonade. Strawberries & Cream.
Pimms.

Was going to suggest raiding your nearest Gails bakery but then saw you need Morrison’s - in which case, some nice bread, cheeses, sliced meats, olives, er... that’d do me! Delicious 😋

Olives.
A quiche.
Nice crisps and a dip.

Champagne or something fizzy, float a couple of strawberries in each glass.

Pate and toast, (salmon or duck). Or a ready made starter like prawn cocktail or avocado and egg salad.

Chicken Caesar salad or poached salmon fillets & salad (don't have two courses of fish though)

Small serving of profiteroles with some strawberries on the side, or ice cream with a splash of liqueur poured over served with some little biscuit thins.

Deli meat
Continental cheese selection
Olives
Crackers / posh bread

Or go houmous, taramaslata, feta, pitta / flatbreads etc.
