Get ready to "possibly" consume cockroaches, mealworms OR crickets.

An extract of the following link: "From 1 January 2018 came into force Regulation (EU) 2015/2238 of the European Parliament and of the Council of 25 November 2015, introducing the concept of “novel foods”, including insects and their parts. One of the most commonly used species of insects are: mealworms (Tenebrio molitor), house crickets (Acheta domesticus), cockroaches (Blattodea) and migratory locusts (Locusta migrans). In this context, the unfathomable issue is the role of edible insects in transmitting parasitic diseases in humans"....https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6613697/

I planted runners and carrots as seedlings then I put them with onions in tubs I got from Lidl which I lined with garden fabric and made holes in bottom.

These containers just cost me about £3 or so from Lidl, perfect for putting on patio, balcony or back yard. Line the sides with garden fabric or bin liners. I got garden fabric from B&M but could be Wilko's or Poundland too.
Then put some holes in with hand drill (very cheap to buy and good for doing holes...there is no noise or electricity needed) or anything else that makes holes. Fill with compost and plant your seedlings. Feed according to needs of plants.

I use egg boxes for seeds first before planting them outside or you can buy so cheap from B&M, Poundland shops those little square seedling planters to put on your windowsill.

Patio peas grown in a pot. Easy peasy to do. Then you can keep peas from pod, dry them and use them as seeds for following year. Apparently they need to be heirloom pea seeds originally (natural polenation) so this will ensure you can reuse the seeds and they will keep on producing a crop.
