We have beaten it but only for an output that's approximately "green smoothie".
We're already better than just LED grow lights for e.g. lettuce, though, from how I recall the linked paper.
Unsure how you conclude that cold outdoors necessitate more meat though; aside from some micronutrients vegan diet works just fine so reverting back to "meat only on Sundays" 1910 style household dinner menu structures would work fine...
Most people could, for example, do with replacing the caloric intake from half the portion of any non-vegan food they consume, with potato.
If outdoor farming breaks from climate meat will get more expensive...
Vertical solar panels mounted like fence panels between fence posts high enough to not get covered by snowdrifts will produce electricity year-round; and we only need around 3x as much solar farm currently to power sealed grow "basements" than the same plant output would need if just farmed on an open field (assuming climate is matched and weather is average). The benefit of it is just that the panels can be other places (like noise barrier walls next to an urban highway) than the plants and the climate can be freely picked. Also no unlucky correlated dry spell weather events that can cut 100 million people's worth of harvest yield down to half or worse.
Grow houses won't fail collectively as much as farming weather is correlated across a region.
Pretty much just need to keep measures around to prevent the plants from freezing just because the electric grid falls over for 3 days in winter.
